AB  - Solvothermaly synthesized zirconium oxide nanopowders, pure and 
doped with various amounts of iron ions (1–20 %), were used as modifiers of 
glassy carbon electrodes. The modified electrodes were tested in the reaction of 
electrochemical oxidation of 2,4,6-trichlorophenol (TCP) in order to inves tigate the influence of doping on electrochemical performance of zirconia mat rix. The techniques of cyclic voltammetry and electrochemical impedance 
spectroscopy were employed. Cyclic voltammetry showed that electrooxid ation of TCP proceeded through the oxidation of hydroxyl group. Possible 
pathway included the formation of quinones and the formation of polyphenol 
film on the electrode surface, leading to the electrode fouling. Iron doping 
enhanced the activity of zirconia matrix towards TCP electrooxidation. Elec trochemical impedance spectroscopy showed the importance of iron content in 
zirconia matrix for the preferable pathway of TCP electrooxidation. The quin one formation pathway was favoured by low iron doped zirconia (doped with 
1% of iron), while polyphenol film formation on the electrode surface was 
more pronounced at samples with higher iron ion content (for doping with 10 
and 20 % of iron). The sample with 5 % of added iron ions, showed intermed
AB  - Нанопрахови цирконијум-оксида, чисти и допирани различитим количинама јона гвожђа синтетисани су солвотермалном методом. Добијени прахови су коришћени као модификатори електродa од стакластог угљеника. Модификоване електроде су тести- ране у реакцији електрохемијске оксидације 2,4,6-трихлорфенола (TCP), како би се испитао утицај допанта на перформансе цирконијум-оксидне матрице. За испитивање су коришћене технике цикличне волтаметрије и електрохемијске импедансне спектро- скопије. Резултати цикличне волтаметрије су показали да се електрооксидација TCP одиграва преко оксидације хидроксилне групе. Могуће даље реакционе путање су укљу- чивале формирање хинона и настајање полифенолног филма на површини електроде који доводи до пасивације електроде. Допирање јонима гвожђа је повећало активност цирконијум-оксидне матрице за електрооксидацију TCP. Резултати електрохемијске импедансне спектроскопије су указали на утицај количине јона гвожђа у цирконијум- -оксидној матрици на реакциони механизам TCP електроосидације. Реакциона путања која укључује формирање хинона је фаворизована на цирконијум-оксидним електро- дама са ниским садржајем јона гвожђа (допираног са 1 % јона гвожђа), док је форми- рање полифенолног филма дошло до изражаја на узорцима са већим садржајем јона гвожђа (допираних са 10 и 20 % јона гвожђа). Узорак цирконијум-оксида, допиран са 5 % јона гвожђа, има прелазна својства, јер долази до формирања полифенолног филма на површини електроде, али и до његове разградње.

AB  - Pure and a series of Fe3+ doped zirconia nanopowders were synthesized combining colloidal chemistry and solvothermal method from organometallic precursors in order to correlate doping and properties of zirconia matrix. After annealing of washed nanopowders at 600 °C, detailed characterization was performed using X-ray diffraction, UV/Vis absorption and luminescence, infrared and electron paramagnetic spectroscopy, transmission electron microscopy and BET measurements. Zirconia samples had mixed monoclinic and tetragonal crystalline phase; increasing Fe3+ ions concentration was followed by increasing of tetragonal phase share. In the sample with highest Fe3+ concentration, hematite can be detected. Also, UV/Vis spectrophotometry showed that Fe3+ doping lowers effective band gap of zirconia matrix from 4.5 eV (bulk value) to 2.1 eV for doped/nanocomposite samples. EPR measurements proved presence of dopant and showed that isolated Fe3+ ions in zirconia matrix exist in both crystalline phases; monoclinic and tetragonal (g ~ 4.8 and g ~ 4.27–4.2, respectively) surroundings. Zirconia samples were also successfully used as photocatalysts for photocatalytic degradation of 2, 4, 6, trichlorophenol.

AB  - Solvothermal synthesis of ZrO2-TiO2 binary oxides and pure counterparts at 150 degrees C in water/isopropanol media is presented. Titanium (IV) isopropoxide and zirconium (IV) propoxide were used as precursors. XRD and TEM techniques were used for structural and morphological characterization of obtained samples. XPS spectra of mixed oxide samples were compared in order to correlate composition of samples with surface properties and presence of defects. Relative positions of defect states within band-gaps of semiconductors were estimated from UCPL spectra. UV-Vis DRS spectra revealed that both pure oxides experienced red shift of absorption thresholds compared to reference data. Photocatalytic activities of all samples were probed under simulated Solar light on three model compounds: phenol, 4-chlorophenol (4-CP) and 2, 4, 6-trichlorphenol (TCP). Pure TiO2 showed the highest photocatalytic activity in the case of phenol. However, pure ZrO2 and binary oxides showed higher photoactivity in degradation of 4-CP and TCP. The activity of wide band-gap semiconductors under simulated Solar light in photodegradation of phenol and its derivatives is most probably the consequence of formation of charge transfer complexes between pollutant molecules and semiconductors surface.

AB  - Solvothermal synthesis of ZrO2-TiO2 binary oxides and pure counterparts at 150 degrees C in water/isopropanol media is presented. Titanium (IV) isopropoxide and zirconium (IV) propoxide were used as precursors. XRD and TEM techniques were used for structural and morphological characterization of obtained samples. XPS spectra of mixed oxide samples were compared in order to correlate composition of samples with surface properties and presence of defects. Relative positions of defect states within band-gaps of semiconductors were estimated from UCPL spectra. UV-Vis DRS spectra revealed that both pure oxides experienced red shift of absorption thresholds compared to reference data. Photocatalytic activities of all samples were probed under simulated Solar light on three model compounds: phenol, 4-chlorophenol (4-CP) and 2, 4, 6-trichlorphenol (TCP). Pure TiO2 showed the highest photocatalytic activity in the case of phenol. However, pure ZrO2 and binary oxides showed higher photoactivity in degradation of 4-CP and TCP. The activity of wide band-gap semiconductors under simulated Solar light in photodegradation of phenol and its derivatives is most probably the consequence of formation of charge transfer complexes between pollutant molecules and semiconductors surface.

AB  - In this paper,a hydrothermal method for synthesis of zirconia nanopowders: pure  and  with  incorporated  Si4+ions  is  presented.  Zirconyl  chloride  and tetraethyl  orthosilicate  were  used  as  precursors.  As  prepared  powders  were annealed  at  600  °C  and  their  structural  (XRD),  morphological  (TEM)  and textural  (BET  method)  properties  were  obtained.It  has  been  shown  that  by using   hydrothermal   synthesis   method   pure   monoclinic   ZrO2highly crystalline    powder    can    be    obtainedwithcrystallites    of    about    25nm. Incorporation  of  Si4+ions  induced  stabilization  of  tetragonal  crystalline phase  at  room  temperature,  decreasing  particle  sizes  to  about  3-6  nm  and increasing specific surface area of nanopowders.

AB  - We report the successful, low temperature synthesis of pure and Fe-doped titania nanoparticle (NP) powders, using organic Ti- and Fe-precursors. The properties of the synthesized titania based materials were obtained using XRD, UV/vis and EPR spectroscopy and BET measurements. The doping of TiO2 induced a shift in the absorption threshold towards the visible spectral range, compared to pure titania. The process of annealing induced an increase in crystallinity and particle sizes in the obtained materials. The photocatalytic activity, using simulated Solar light (Vitalux lamp), of our samples was checked by following the photodegradation reaction of Rhodamine B and trichlorophenole as model compounds.

AB  - ZnO/ZnWO4 composite rod-like nanoparticles were synthesized by low-temperature soft solution method at 95 A degrees C with different reaction times (1-120 h), in the presence of non-ionic copolymer surfactant Pluronic F68. Obtained nanoparticles had diameters in the range around 10 nm and length of 30 nm. Optical properties such as reflection and room temperature photoluminescence of obtained samples showed strong dependence on their crystallinity and composition. Photocatalytic activity of ZnO/ZnWO4 nanopowders was checked using photodegradation of selected dyes as model system. Obtained results were correlated with specific surface area, particle sizes, crystallinity and ZnO/ZnWO4 ratio of the samples. As crystallinity of ZnWO4 component in the ZnO/ZnWO4 increase, photocatalytic activity also increases. The main findings can be explained by charge transfer reactions that follow light absorption by ZnO and ZnWO4 in nanocomposite.
