AB  - Titan(IV)-oksid je jedan od najčešće korišćenih fotokatalizatora, dok za polipirol (PPy) postoje potvrde da je pogodan za ovu primenu. Cilj ovog rada bio je dobijanje kompozita TiO2/PPy sa boljom fotokatalitičkom aktivnosti u odnosu na TiO2. Kako bi se optimizovao sadržaj PPy u kompozitu, sintetisani su uzorci TiO2/x%PPy (x = 0, 0,5, 1, 1,5, 3, 5 mas.%), koji su okarakterisani TG/DTA, XRD, FTIR, FESEM i UV-Vis metodama, dok su njihova fotokatalitička svojstva ispitana kroz razgradnju tekstilne boje RO16. Nanokristalni TiO2 je dobijen u obliku anatasa veličine kristalita oko 2 nm, dok su izračunati parametri jedinične ćelije potvrdili da je kristalna struktura anatasa ostala nepromenjena nakon dodatka PPy. Gotovo svi uzorci (izuzev TiO2/3%PPy) su fotokatalitički aktivniji od TiO2, dok je TiO2/1%PPy pokazao najizraženiju fotokatalitičku aktivnost razgradivši 9 % boje nakon 75 min.
AB  - Titanium(IV) oxide is one of the most used photocatalysts while polypyrrole (PPy) is a promising material for photocatalytic application. The aim of this work was to obtain TiO2/PPy composites exhibiting higher photocatalytic activity than TiO2. In order to determine the optimal PPy content in a composite, TiO2/x%PPy (x = 0, 0.5, 1, 1.5, 3, 5 wt.%) samples were synthesized and characterized by TG/DTA, XRD, FTIR, FESEM and UV-Vis methods, while the photocatalytic behavior was examined towards the degradation of the textile dye RO16. Nanocrystalline TiO2 was obtained in anatase form with crystallite size around 26 nm and preserved anatase crystal structure despite the addition of PPy according to the calculated unit cell parameters. Almost all samples (except TiO2/3%PPy) showed better photocatalytic activity than TiO2 while the best photocatalytic activity was demonstrated by TiO2/1%PPy which degraded 98 % of the dye after 75 min.

AB  - Zinc oxide nanoparticles (ZnO-NPs) have been a subject of numerous researches owing to their multifunctional properties in many applications, such as solar cells, UV light-emitting devices, gas sensors and photocatalysts. ZnO-NPs can be synthesized through various methods and their features can be tailored by shape and size, resulting in new applications relevant to their structural properties. The synthesis of ZnO-NPs via controlled thermal decomposition of the single-source precursors represents a novel synthetic methodology. The basic goal of this study was to investigate the influence of precursors on crystallite size and morphology of the resulting ZnO-NPs. Four structurally characterized Zn complexes with different benzenepolycarboxylato ligands [1] were used as precursors for investigation of photocatalytic and antimicrobial effects of thermally obtained ZnO-NPs. The XRPD and FESEM analysis of ZnO-NPs, prepared by thermolysis of Zn precursors at 450 °C in the air atmosphere, revealed hexagonal wurtzite structure (space group P63mc, a ≈ 3.25 and c ≈ 5.21 Å) with an average crystallite size in the range of 39–47 nm and similar morphology. The best photocatalytic activity for degradation of Reactive orange 16 dye has been observed for ZnO-NPs where crystallites form the smallest agglomerates. All obtained ZnO-NPs showed excellent inhibitory effect against Gram-positive bacteria Staphylococcus aureus and Gram-negative bacteria Escherichia coli.
