    A2. Photocatalytic processes with TiO2 nanostructured materials  




    A. Catalytic-photocatalytic reactions for environmental detoxification (Advanced Oxidation Processes) and synthesis of nanostructured materials with environmentally friendly methods

    Metal oxides, mainly TiO2, and polyoxometallates (POM) mainly of W, have been used in thermal and mainly photochemical reactions according to the following photocatalytic cycle:

    POM upon illumination at the O → M CT band (i.e., in UV and near-visible area) become powerful oxidizing reagents able to oxidize various organic compounds. In the process POM undergo stepwise reduction accumulating electrons that can be subsequently delivered, via thermal reactions to a variety of oxidants. This way a great variety of organic compounds are oxidized and indeed mineralized to CO2, H2O and inorganic anions and several organic and inorganic compounds can be reduced via a photocatalytic process in which POM serve as electron relays. Thus, in principle, POM can serve as decontamination photocatalysts of aquatic media removing both organic pollutants and metal ions. Under special conditions controlled photocatalytic reactions have been reported. In addition, the reduction-precipitation of metal ions mediated by POM may lead to formation of metal nanoparticles in which POM serve as reducing reagents and stabilizers. Our main contribution has been with the use of POM in the following areas, (representative references are given in parentheses):

    [top of page]

    (a) Non-selective oxidation (photodegradation) of organic pollutants to CO2, H2O and inorganic anions

    The above method has been applied to many organic pollutants, such as phenol, chlorophenols and chloroacetic acids [12, 3, 4, 5]. OH radicals generated by reaction of POM with H2O seem to play a key role in the process. Dioxygen is important in that it oxidizes (regenerates) the catalyst and through reductive activation may or may not participate further in the process, depending on the substrate [6]. Due to their photocatalytic performance, POM can be recognized as a new AOP. Recently, the photocatalytic degradation of some diversified pesticides has been performed. Among the target pesticides was lindane [7], a typical organochlorine insecticide with a very high stability in the environment, the organophosphorous insecticide fenitrothion [8], the herbicide atrazine [9], and the acid herbicide, bentazone [10]. In all cases, the final degradation products were CO2, H2O, and inorganic anions, with the exception of atrazine, which is degraded into the non-toxic but persistent cyanuric acid. Several intermediates have formed prior to mineralization giving rise to complicated degradation mechanisms. As an example, the intermediates detected in case of fenitrothion are presented in the following scheme.

    POM are at least as effective as the widely published TiO2. Both systems have been compared in parallel experiments and there has been demonstrated their similarity in terms of the overall photocatalytic performance, intermediates and final degradation products [8].

    (b) Reduction-removal of metallic ions

    Recently, a novel photocatalytic method for the selective reduction and recovery of several metal ions from their aqueous solutions based on POM has been reported. By suitable choice of POM and organic substrate, several metal ions (Ag+, Cu2+, Pd2+, Au3+, Hg2+, Ni2+, Cr6+), can be reduced to a lower or zero oxidation states. This way, photocatalytic decontamination of aqueous solutions, from organic pollutants and metal ions can take place, upon illumination in the presence of POM [1, 2, 3, 4, 5, 6].

    [top of page]

    (c) Reductive decomposition of organic compounds

    In a photocatalytic mode, the excited POM, produced after absorption of UV-near visible light, is a strong oxidant capable of mineralizating a variety of organic species, including organic pollutants to CO2 and inorganic anions. Reduced POM can deliver their electrons to great variety of chemical species, such as O2, H+, nitroaromatics and metal anions among others. Resently, POM (PW12O403- and SiW12O404-) are proposed as efficient photo-catalysts for the reductive degradation of the azo dyes Acid Orange 7 (AO), Naphthol Blue Black (NB) and Disperse Blue 79 in aqueous or ethanol solutions [1, 2, 3]. The process involves absorption of light by polyoxometalates, oxidation of an organic sacrificial electron donor, for instance propan-2-ol or ethanol, and the subsequent reductive destruction of the azo dye by reduced POM with the concomitant recycling of the POM catalyst to the oxidized form. Results show that the dyes are reduced to aromatic amine derivatives. On the other hand, photooxidative decomposition of azo dyes, that also takes place, involves again absorption of light by POM followed by direct or OH-mediated oxidation of the dye. This process is an order of magnitude slower than reductive elimination, but leads to mineralization of the azo dye [3].

    (d) Controlled size synthesis of metal nanoparticles

    We have recently shown that by keeping the ionic strength low, illumination of a (Substrate/POM/Mn+) solution leads to formation of metal nanoparticles, through a process in which POM serve both as photocatalysts-reducing reagents and stabilizers [1, 2, 3].

    According to the following reactions:

    POM + S ------> POM(e-) + Sox

    POM(e-) + Mn+ ---------> POM + M0coll

    (S = organic substrate, Mn+ = metal ion)

    metal nanoparticles with average diameter less than ca 15 nm and small size distribution (< 25%) have been formed from Ag+, Pd2+, Au3+ and Pt4+.



     A. Troupis, et al., Angewandte Chemie Intrnational Edition, 2002, 41, 1911-1914


    The process exhibits both practical and academic interest. From the practical point of view, it involves an environmental friendly and simple way to synthesize metal nanoparticles since: (a) It takes place at room temperature, rapidly, within a few seconds, utilizing a mild reductant, i.e. SiW12O405– (0.057 V vs. NHE) in catalytic amounts. On the other hand, other reducing methods that proceed at room temperature need extremely strong reductants such as BH4 –, hydrogen atoms, solvated electrons or organic radicals that are formed upon radiolysis with γ-rays or sonolysis of aqueous solutions, while other methods that utilize mild reductants request high-stoichiometric amounts and heat in order to complete even after hours or days. (b) The synthesis of metal nanoparticles is achieved in water, a non-toxic solvent. (c) POM, besides reductant, serves also as stabilizer, avoiding the addition of a second, sometimes toxic, reagent that would be needed to arrest the metal particles in nano-dimensions.

    The fact that the above reactions can be separated in time and space makes size selectivity of metal nanoparticles to be achieved on the basis of rate control of Mn+ reduction. The unique ability of POM to exhibit widely varied and precisely controlled redox potentials depending on intrinsic properties could extent the applications of this size selective process [4].

    Verification of our previous studies according to which POM serve as both reducing reagents and stabilizers in synthesis of metal nanoparticles has been achieved by characterization of nanoparticles using high resolution transmission electron microscopy (HRTEM) [5]. The figure below is a representative HRTEM image of one Se0 crystal nanoparticle produced upon photolysis of SiW12O404- /propa-2-ol to form one-equivalent tungstate, SiW12O405- and addition of Se(IV). An amorphous shell, 1–3 nm thick, surrounds the Se crystalline core.


    This shell was studied by energy filtered transmission electron microscopy (EFTEM). The EFTEM images represent elemental maps, where a bright area indicates a high elemental concentration. The images presented below are evidence that the core of the nanoparticles is Se, while the surrounding shell is composed of O, Si and W, that is, POM.

    (e) Inorganic-Organic Multilayer Films based on Polyoxometalates

    Most of the studies on POM have focused on homogeneous solutions. Although homogeneous decontamination is a useful process, POM present a disadvantage for the recovery of catalyst, which is necessary in many cases. Therefore immobilization of these catalysts is very important. In this frame, original photochromic and photocatalytic multilayer films are produced by the polyoxometalate (POM) SiW12O404- and poly(ethylenimine), via the layer-by-layer (LbL) self-assembly method. The resulting multilayer films have been characterized by UV-Vis spectroscopy, FTIR and atomic force microscopy (AFM) [1]. Irradiation with ultraviolet-near visible light of this composite material causes reduction to POM (SiW12O405-), while the films acquire the characteristic blue color of reduced POM. Oxygen plays a great part in the gradual reoxidation of the coated POM, resulting in the reversible photochromism of the films.

    A2. Photocatalytic processes with TiO2 nanostructured materials

    (a) Photodegradation of organic pollutants by TiO2 .Elucidation of the reaction mechanism

    The photocatalytic degradation of bromomethanes (CBr4, CHBr3 and CH2Br2) and halomethanes containing chlorine and bromine (CCl3Br, CHCl2Br, CH2ClBr) or bromine and fluorine (CBr3F) over irradiated TiO2 has been investigated under aerobic and anaerobic conditions. For all of those compounds, the complete disappearance of the primary compound and the stoichiometric concentration of halides was achieved. Degradation proceeds through combined reductive and oxidative processes [1, 2].

    The photocatalytic degradation of the organophosphorus insecticide diazinon in aqueous suspensions has been studied by using TiO2. The degradation of the insecticide was a fast process and included the formation of several intermediates that were identified using GC/ion-trap mass spectrometry with EI or CI in positive and negative ionization mode and HPLC/electrospray-QqTOF mass spectrometry. Since primarily hydroxyl derivatives were identified in these aqueous suspensions, the mechanism of degradation was probably based on hydroxyl radical attack [3].

    Recently, in the frame of the European Project “CleanWater” highly efficient N- and N-F- doped TiO2 nanoparticles with enhanced structural properties and high photocatalytic activity under visible light irradiation have been used for the degradation of microcystin-LR (MC-LR), geosmin (GSM) and 2-methyl-isoborneol (2-MIB) (unpublished results).

    (b) Comparison of the photoredox properties of polyoxometallates and semiconducting particles

    We have demonstrated that two large categories of compounds, namely, polyoxometallates and aggregates of various metal oxides have similar properties. Emphasis was given to the photocatalytic properties of the two systems in terms of the overall mechanism of photodecomposition of organic compounds, the intermediate species involved and the final photodegradation products (i.e., CO2, H2O and inorganic anions) [1]. The similarity of behavior has been attributed to the formation of the common powerful oxidizing reagent, OH radical, from the reaction of the excited catalyst and water molecules. Further studies provide substantial evidence that the apparent photooxidation mechanism of these two categories of photocatalysts is circumstantial, depending on substrate and the mode of investigation. Overall, though, the action of OH radicals relative to h+ appears to be more pronounced with PW12O403than TiO2 [2].

    B. Environmental Analytical Chemistry

    Development of Methods for the determination of toxic pollutants in trace level in water, foodstuff and environmental samples

    Contamination of water supplies with organic pollutants such as PAHs, PCBs, pesticides and hazards of biogenic origin, i.e., cyanotoxins is one of the most important global problems. Recent EU Directives propose the determination of these target pollutants in drinking and surface water and set their maximum concentration. Resulting from the above, it is mandatory to monitor these analytes using appropriate methods. The development of new advanced analytical methods can give rise to sensitive and reliable determinations even at the ppt level. Our contribution to this area of research can be summarized into the following:

    [top of page]

    (a) Development of Methods for the determination of cyanotoxins in surface and drinking water by using SPE and LC/MS-MS

    Cyanobacteria (blue-green algae) are considered an important water quality problem, since several genera can produce toxins, known as cyanotoxins that are harmful to human health. Blooms of toxic cyanobacteria have been reported worldwide and several incidents of wild and domestic animal poisoning as well as human injury and death have been reported. Hepatotoxic cyclic peptide toxins (microcystins, MCs, and nodularins) are the most widespread cyanotoxins that are present in diverse environments [1]. MCs are cyclic heptapeptides that are produced by different cyanobacteria genera such as Microcystis, Anabaena, Plankothrix and Nostoc. About 80 MC variants have been identified so far in natural water samples and cyanobacterial cultures, with microcystin-LR (MC-LR) being the most common and most toxic variant. Nodularins are similar toxic cyclic pentapeptides that are produced by different cyanobacterial strains of the genera Nodularia whereas motuporin, a structural analog of nodularin, was isolated from a marine sponge. During the last years there is a growing concern regarding the health effects of MCs and nodularins, because they act as tumor promoters, through the inhibition of protein phosphatases 1 and 2A, which play a key role in cell regulation. In response to this concern, WHO has recommended for provisional adoption the value of 1 μg/L as a Guideline Value for MC-LR concentration in drinking water. This has resulted to the need for development of reliable analytical methods for the monitoring of this class of toxins in water supplies on a quantitative basis.

    Our contribution was focused on the development of a system of analytical methods that addresses large scale monitoring of MCs (MC-RR, MC-YR, MC-LR, MC-LA) and NOD in surface and drinking waters. To accomplish this goal, ELISA and PPIA were used for primary quantitative screening of the target compounds, while HPLC/PDA and LC/MS/MS methods were applied to positive samples. The methods employed were validated in-house and method performance parameters were estimated. In addition, a protocol of analysis of unknown samples was developed, that uses the above methods, with the aim to serve as a cost-effective system for the analysis of large numbers of water samples. The validity of this system was tested through analysis of a number of real surface and drinking water samples. For the first time, the fitness for purpose of this analytical protocol has been discussed, with respect to analytical performance as well as time and cost of analysis [2].

    In the area of research on identification of cyanotoxins, a fast and selective method for the sensitive determination of anatoxin-a in lake waters using LC/MS-MS and phenylalanine-d5 as internal standard, has been developed [3].
    Anatoxin-a (AN) is an alkaloid neurotoxin, produced by the freshwater blue-green algae genera Anabaena, Oscillatoria, Aphanizomenon, Cylindrospermum, Microcystis, Oscillatoria, Planktothrix andRaphidiopsis. Massive proliferation of neurotoxic cyanobacteria producing anatoxin-a in waterbodies around the world has resulted in fatal intoxications of several wild and domestic animals with significant environmental and economic consequences. Τhe Department of Health of Washington State recommends the use of 1 μg L−1 as a provisional value in order to provide an adequate margin of drinking water safety.Phenylalanine is a natural amino acid, also present in freshwaters, isobaric to anatoxin-a, with a very similar fragmentation pattern and LC retention. Since misidentification of phenylalanine as anatoxin-a has been reported in forensic investigations, special care must be taken in order to selectively determine traces of anatoxin-a in the presence of naturally occurring phenylalanine. In the method developed a 1.8 μm 50×2.1 mm C18 column was used for the separation of anatoxin-a and phenylalanine, achieving a 3-min analysis time. Isotopically labelled phenylalanine-d5 was employed as internal standard to compensate for electrospray ion suppression and sample preconcentration losses. Both compounds were preconcentrated 1,000-fold on a porous graphitic carbon SPE cartridge after adjustment of sample pH to 10.5. The method was validated by using spiked lake water samples. Anatoxin-a recovery ranged from 73 to 97%, and method LOD and LOQ were 0.65 and 1.96 ng L−1 respectively [3].

    (c) Development and validation of a new analytical method for  high sensitivity analysis of European Union 8 priority pollutant PAHs in surface and drinking water by LC/APPI/MS-MS

    The developed method for PAHs determination using LC/APCI-APPI/MS-MS (unpublished results) fulfils established criteria imposed by recent legislation on environmental quality standards in the field of water policy. Various APCI and/or APPI conditions were tested and various dopants were examined in order to achieve best ionization of the selected polycyclic aromatic hydrocarbons (PAHs) (naphthalene (Naphth), anthracene, (Anthr) fluoranthene, (Fluor) benzo(b)fluoranthene (B(b)F), benzo(k)fluoranthene (B(k)F, benzo(a)pyrene, (B(a)P) benzo(g,h,i)perylene (B(g,h,i)P) and indeno(1,2,3-c,d)pyrene (Indeno)). The APCI-APPI/MS–MS operating conditions were optimized on the basis of mass spectral data and two specific transitions per compound were selected for simultaneous monitoring in SRM mode. The procedure, based on SPE extraction before analysis by LC/MS–MS, was fully validated on the basis of international protocols. Recovery and within-laboratory reproducibility for all target compounds studied were satisfactory. Low LODs were established with this method for the majority of PAHs. The proposed method proved to be a valuable tool for assessment of the occurrence of PAHs in surface and potable water samples and can be adapted for routine application in monitoring studies and surveys.

    1.«Cyanobacterial blooms and toxins in water resources: Occurrence, impacts and management», COST Action ES1105, 2012 – 2016, Grant Holder: NCSR “DEMOKRITOS”, Budget per year:~180 K.

    Over 60 partners (scientists, other professionals and companies), from 32 European countries as well as from USA, participate in this Action. The main objective of the Action is to increase, disseminate and harmonize capabilities across Europe for the risk management of cyanobacteria and cyanotoxins in water bodies, by establishing strong and synergistic links between academia, authorities, industry and citizens.

    The achievement of the above objective requires inter-and multidisciplinary efforts. A strong and integrated consortium of Action has been developed and includes scientists and researchers with recognized expertise in analytical chemistry, molecular biology, aquatic/catchment ecology, toxicology and water engineering plus end-users and stakeholders (public authorities, water supply utilities, industry). This arrival of this Action is timely because new challenges in the field have appeared recently including emerging toxins and cyanobacterial species hitherto unknown in Europe, leading to the preparation of new legislation and regulations in some European countries.
