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.
