AB  - Beside wide range of applications, zinc oxide is recently recognized as a promising photocatalyst mainly used to degrade organic water pollutants. The great advantage of ZnO over TiO2, which is the most common photocatalyst, is the absorption in wider solar spectrum, partly in the visible region [1]. Generally, the photocatalytic properties usually depend on the crystallinity and crystallite size, particle size, morphology and pore sizes, surface area, band gap energy, availability of active sites, number and nature of trapped sites, as well as on adsorption/desorption characteristics [2]. The modification of photocatalysts by noble metals can enhance their photocatalytic activity. This paper discuss the influence of synthetic method on photocatalytic activity of obtained powders.
Solvothermal and precipitation methods were chosen for the preparation of Ag/ZnO nanopowders. For the first one, the Zn(CH3COO)2·2H2O with different AgNO3 content (0, 0.75, 1.5 and 3 mol.%) was solvothermally treated at 120 °C for 18 h in the presence of poly(vinyl pyrrolidone), ethylene-glycol and NaOH. The obtained samples were rinsed out with distilled water, centrifuged and dried at 105 °C for 3h. In precipitation method, Zn(CH3COO)2·2H2O was dissolved in ethylene-glycol in the presence of chitosan soluted in acetic acid, which was followed by addition of AgNO3 in the same quantity as used for the solvothermal synthesis. The obtained suspension was heated up to 150 °C for 2 h and then calcined at 400 °C for 1 h (Fig.1).
The prepared samples were characterized by XRPD, FESEM, UV-vis techniques, while photocatalytic properties were tested on Reactive Orange 16 textile azo dye and compared to the commercial ZnO (the average particle size: 20 nm).
84
Based on XRPD, the predominant phase in all samples is ZnO with the weak reflections belonging to Ag for 0.75%Ag/ZnO, which become clearly visible for samples with 1.5 and 3% of Ag. The average crystallite size was calculated using Williamson-Hall method giving 20 ± 2 and 25 ± 2 nm for powders obtained by solvothermal and precipitation method, respectively. The calculated strains were insignificant probably due to low concentration of defects. On the other hand, this is not the case for commercial ZnO with strain of 0.25(3) %. This sample consists of nanoparticles with a slightly elongated spherical shape while all obtained ZnO nanopowders contain mutually similar nanoparticles with approximately spherical shape, which however create diverse forms of agglomerates. The average particle size was around 25 nm for solvothermally synthesized samples and approximately 30 nm for samples obtained by precipitation method.
Comparing to both unmodified ZnO and commercial one, all prepared Ag/ZnO samples showed a broad band at 450 nm (visible region) which causes the narrowing of band gap. The existence of this band is the confirmation that metallic Ag particles were formed, as indicated by XRPD, since they can absorb visible light and activate photocatalyst in visible spectrum.
The photocatalytic measurements showed that all synthesized nanopowders have higher adsorption power and photocatalytic activity than the commercial ZnO (Fig.1). This could be attributed to slightly elongated grains of commercial ZnO and the existence of significant strain. If compare the samples obtained by two different methods, Ag modified ZnO powders from solvothermal method are more efficient than the ones from precipitation method due to the smaller particles of silver.Larger Ag particles on ZnO could cause negative effects, such as light blocked, which result in the decrease of photocatalytic activity. The unmodified ZnO powders have the same efficiency regardless of the synthetic method. Comparing the photocatalytic activity of samples obtained by same method, the Ag distribution and its particle size seems to play the major role.
Summary, no matter which procedure was used, 1.5% Ag/ZnO powders have performed the highest effciency in degradation of RO16. It means that the photocatalytic activity does not depend only on Ag content but the metal distribution is important as well. In this work, it is shown that the optimized content of Ag amounts about 1.5 mol.% regardless of synthetic method and it could be recommended for further research in terms of economy.

AB  - TiO2 nanopowders were produced by sol-gel technique using TiCl4 as a starting material. For the preparation of crystalline anatase with developed surface area, this aqueous solution has been mixed with 0.05 M or 0.07 M (NH4)(2)SO4 solution in a temperature-controlled bath. The pH values of the suspension were 7, 8 or 9. According to the x-ray diffraction (XRD) analysis the anatase crystallite sizes were about 12 nm, which coincided with the average particle size revealed by scanning electron microscopy (SEM). The Raman scattering measurements have shown the presence of a small amount of highly disordered brookite phase in addition to dominant anatase phase with similar nanostructure in all synthesized powders. BET measurements revealed that all synthesized catalysts were fully mesoporous, except the sample synthesized with 0.07 M (NH4)(2)SO4 at pH=9, which had small amount of micropores. The photocatalytic degradation of herbicide Clomazone was carried out for both the pure active substance and as the commercial product (GAMIT 4-EC) under UV irradiation. The best photocatalytic efficiency was obtained for the catalyst with the largest specific surface area, confirming this parameter as crucial for enhanced photocatalytic degradation of the pure active substance and commercial product of herbicide Clomazone.

AB  - Zinc oxide is a well-known photocatalyst mainly used to degrade organic water 
pollutants using artificial or sunlight. It is one of the most widely used material because of its 
good photoactivity, biological and chemical stability, wide band gap and low cost [1]. Its 
photocatalytical properties depend on surface area, availability of active sites, pore sizes, 
number and nature of trapped sites, as well as on adsorption/desorption characteristics. On the 
other hand, the modification of semiconductor photocatalysts by noble metals can enhance 
their photocatalytic activity. 
The Zn(CH3COO)2·2H2O with different AgNO3 content (0, 0.75, 1.5, 3 and 6 mole%) 
was solvothermally treated in the presence of poly(vinyl pyrrolidone) as surfactant. The 
obtained samples were rinsed out with distilled water, centrifuged and dried at 105 °C for 3h. 
The specimens were characterized by XRD, FESEM and TEM techniques. The photocatalytic 
activity of the nanocrystalline powders was tested on the Reactive Orange 16 (RO16) textile 
azo dye and compared to the commercial ZnO (the average particle size: 20 nm).
The results showed that Ag modified samples consist of ZnO nanocrystals with
hexagonal wurtzite structure and metallic Ag with face-centered-cubic structure. There is no 
remarkable shift of diffraction peaks of the ZnO, meaning that Zn1-xAgxO1 solid solution is not 
formed and hence the change of unit cell parameters of ZnO nanocrystals is negligible. The 
average crystallite size of all samples was about 20 nm, as determined by XRD analysis from 
Williamson-Hall plots, and confirmed by TEM. The FESEM revealed the uniformity in size 
and approximately spherical shape of the nanoparticles. Ag nanograins were located on the 
surface of ZnO nanoparticles.
It was shown that all synthesized samples have a higher adsorption power and 
photocatalytic activity than the commercial ZnO. Also, Ag modified ZnO powders are more 
efficient than the unmodified one. The samples containing 1.5 and 0.75 mole% of Ag 
respectively, demonstrate the best photocatalytic activity. According to FESEM, this is due to 
the well distributed Ag nanograins over ZnO nanoparticles in the case of these two samples.

AB  - Cink-oksid je poznati fotokatalizator koji se uglavnom koristi za razgradnju organskih 
zagađujućih suspstanci u vodi uz pomoć veštačke ili sunčeve svetlosti. Zbog svoje dobre 
fotoaktivnosti, biološke i hemijske stabilnosti, široke zabranjenje zone i ekonomičnosti ZnO 
spada u jedan od najčešće korišćenih materijala [1]. Njegova fotokatalitička svojstva zavise od 
specifične površine, dostupnosti aktivnih mesta, veličine pora, broja i prirode blokiranih mesta, 
kao i od karakteristika procesa adsorpcije/desorpcije. S druge strane, modifikovanje 
poluprovodnog fotokatalizatora plemenitim metalima može povećati fotokatalitičku aktivnost.
Zn(CH3COO)2·2H2O sa različitim sadržajem AgNO3 (0; 0,75; 1,5; 3 i 6 mol. %) tretiran 
je solvotermalnim postupkom u prisustvu površinski aktivne materije polivinil pirolidona. 
Dobijeni uzorci ispirani su destilovanom vodom, centrifugirani i sušeni na 105 °C tokom 3 h. 
Uzorci su okarakterisani rendgenskom difrakcijom, „field emission“ skenirajućom 
elektronskom mikroskopijom (FESEM) i transmisionom elektronskom mikroskopijom (TEM). 
Fotokatalitička aktivnost dobijenih nanokristalnih prahova ispitana je na tekstilnoj azo-boji 
Reactive Orange 16 (RO16) i upoređena je sa kupovnim ZnO (srednja veličina čestica: 20 nm).
Rezultati su pokazali da se uzorci modifikovani sa Ag sastoje od ZnO nanokristala sa 
heksagonalnom vircitnom strukturom i metalnog Ag sa pljosno centriranom teseralnom 
strukturom. Nije uočeno značajnije pomeranje difrakcionih pikova ZnO, a samim tim ni 
promena parametara jedinične ćelije, što znači da nije nastao čvrsti rastvor Zn1-xAgxO1. Srednja 
veličina kristalita kod svih uzoraka bila je oko 20 nm, što je određeno renedgenskom 
difrakcijom na nanokristalnim uzorcima pomoću Vilijamson-Holove metode i potvrđeno 
TEM-om. FESEM je ukazao na uniformnost veličine i na približno sferni oblik nanočestica. 
Nanozrna Ag nalaze se na površini nanočestica ZnO.
Svi sintetisani uzorci imaju veću adsorpcionu moć i fotokatalitičku aktivnost u odnosu 
na kupovni ZnO. Takođe, prahovi ZnO modifikovani sa Ag efikasniji su nego nemodifikovan 
ZnO. Uzorci sa 1,5 i 0,75 mol. % Ag pokazuju najbolju fotokatalitičku aktivnost, a razlog je 
fina raspodela nanozrna Ag na nanočesticama ZnO, što se može uočiti na FESEM-u za ova dva 
uzorka.

Serb. Chem. Soc. 79 (2014) 1433-1443., Cink-oksid je poznati fotokatalizator koji se uglavnom koristi za razgradnju organskih 
zagađujućih suspstanci u vodi uz pomoć veštačke ili sunčeve svetlosti. Zbog svoje dobre 
fotoaktivnosti, biološke i hemijske stabilnosti, široke zabranjenje zone i ekonomičnosti ZnO 
spada u jedan od najčešće korišćenih materijala [1]. Njegova fotokatalitička svojstva zavise od 
specifične površine, dostupnosti aktivnih mesta, veličine pora, broja i prirode blokiranih mesta, 
kao i od karakteristika procesa adsorpcije/desorpcije. S druge strane, modifikovanje 
poluprovodnog fotokatalizatora plemenitim metalima može povećati fotokatalitičku aktivnost.
Zn(CH3COO)2·2H2O sa različitim sadržajem AgNO3 (0; 0,75; 1,5; 3 i 6 mol. %) tretiran 
je solvotermalnim postupkom u prisustvu površinski aktivne materije polivinil pirolidona. 
Dobijeni uzorci ispirani su destilovanom vodom, centrifugirani i sušeni na 105 °C tokom 3 h. 
Uzorci su okarakterisani rendgenskom difrakcijom, „field emission“ skenirajućom 
elektronskom mikroskopijom (FESEM) i transmisionom elektronskom mikroskopijom (TEM). 
Fotokatalitička aktivnost dobijenih nanokristalnih prahova ispitana je na tekstilnoj azo-boji 
Reactive Orange 16 (RO16) i upoređena je sa kupovnim ZnO (srednja veličina čestica: 20 nm).
Rezultati su pokazali da se uzorci modifikovani sa Ag sastoje od ZnO nanokristala sa 
heksagonalnom vircitnom strukturom i metalnog Ag sa pljosno centriranom teseralnom 
strukturom. Nije uočeno značajnije pomeranje difrakcionih pikova ZnO, a samim tim ni 
promena parametara jedinične ćelije, što znači da nije nastao čvrsti rastvor Zn1-xAgxO1. Srednja 
veličina kristalita kod svih uzoraka bila je oko 20 nm, što je određeno renedgenskom 
difrakcijom na nanokristalnim uzorcima pomoću Vilijamson-Holove metode i potvrđeno 
TEM-om. FESEM je ukazao na uniformnost veličine i na približno sferni oblik nanočestica. 
Nanozrna Ag nalaze se na površini nanočestica ZnO.
Svi sintetisani uzorci imaju veću adsorpcionu moć i fotokatalitičku aktivnost u odnosu 
na kupovni ZnO. Takođe, prahovi ZnO modifikovani sa Ag efikasniji su nego nemodifikovan 
ZnO. Uzorci sa 1,5 i 0,75 mol. % Ag pokazuju najbolju fotokatalitičku aktivnost, a razlog je 
fina raspodela nanozrna Ag na nanočesticama ZnO, što se može uočiti na FESEM-u za ova dva 
uzorka.

AB  - TiO2 nanopowders were produced by sol-gel technique using TiCl4 as the starting
material. For the preparation of anatase crystalline, this aqueous solution was the mixed with
0.05 M and 0.07 M (NH4)2SO4 solution in a temperature-controlled bath. PH values of the
solutions were 7, 8 and 9, respectively. Structural, morphological and surface properties of
synthesized TiO2 nanopowders were investigated by XRD, SEM, and BET measurements.
The crystallite sizes determined by XRD measurements had range about 12 nm, and this was
confirmed by SEM. The photocatalytic degradation of the pure active substance and commercial product (GAMIT 4-EC) of herbicide clomazone (0.05 mM) in aqueous
suspensions of synthesized and commercial (Degussa P25) TiO2 were examined under UV
radiation. In all experiments the concentration of the catalyst was 0.50 mg mL-1. BET
measurements revealed that all synthesized catalyst had mesoporous structure, except the
sample synthesized with 0.07 M (NH4)2SO4 and at pH of solution 9 that had small amount of
micropores. This sample had the best photocatalytic properties, even better than commercial
Degussa P25, and the reason of that is rather the biggest porosity than the combination of
micro- and mesoporosity.

AB  - The effects of common precursors used in the synthesis of CeO2 nanopowders were investigated, and the structural and spectral properties of the resulting products were compared. Two cerium (III) salts, i.e., Ce(NO3)(3)center dot 6H(2)O and CeCl3 center dot 7H(2)O, and two cerium (IV) salts, i.e., Ce (SO4)(2)center dot 4H(2)O and (NH4)(2)Ce(NO3)(6) were applied. The proposed procedures for the CeO2 preparations were realizdd using the same hydrothermal treatment conditions. The products were characterized using X-ray powder diffraction (XRD) and thermogravimetric (TG) analysis, and the morphology was determined using scanning (SEM) and transmission electron microscopy (TEM). The spectral properties of the obtained nanopowders were characterized by FT-IR, Raman scattering and UV-vis spectroscopy. The results revealed the influence of the precursors on the crystallinity, crystallite size, band gap energy, morphology and purity of the synthesized samples.

AB  - In this work, zinc oxide powders were obtained by two different techniques: hydro- and solvothermal synthesis starting from Zn(NO3)(2) and Zn(CH3COO)(2), respectively. The influence of synthetic procedure on the structural, microstructural, thermal and photocatalytic properties of the prepared ZnO powders was investigated. Both ZnO samples were further annealed under moderate conditions (300 degrees C) to avoid grain growth and to remove traces of impurities. In all four cases, single-phase hexagonal ZnO was confirmed by X-ray powder diffraction. The morphologies of prepared ZnO powders were different and they varied from rounded nanograins to microrods. All prepared samples showed higher photocatalytic efficiency in the degradation of the textile azo dye Reactive Orange 16 (RO16) than commercial ZnO. In addition, the non-annealed samples had better photocatalytic properties than the commercial Degussa P25 TiO2 powder.

Four different salts of cerium were used as starting materials for the synthesis as the
precursors: two salts of cerium (III): Ce(NO3)3·6H2O and CeCl3·7H2O, and two salts
of cerium (IV): Ce(SO4)2·4H2O and (NH4)2Ce(NO3)6. The precipitated precursors
were washed and then subjected to hydrothermal treatment at 200 ºC during 18 h. In
some cases hydrothermally prepared samples were annealed at higher temperature to
obtain phase-pure samples. The phase identification of the samples and analysis
were carried out by X-ray diffraction, FTIR spectroscopy, and TG/DSC analysis.
