Özet
TiO2 was doped with Se(IV) ions to obtain a visible light active photocatalyst with high photocatalytic activity. In order to characterize and describe the effect of Se(IV)-doping on the electronic and structural properties of TiO2, a combination of experimental structural methods and DFT calculations were used. A series of Se(IV)-doped photocatalysts with different Se(IV) contents were prepared by an incipient wet impregnation method, followed by calcination at 623, 723 and 823K for 1h, 3h and 5h. The Se(IV)-doped photocatalysts were characterized by XRD, XPS, UV-DRS, FESEM, EDX, HR-TEM and surface area (BET) measurements. A high visible light absorption band from 420nm extending up to 650nm in the UV-DRS was obtained. The photocatalytic activity of the Se(IV)-doped TiO2 photocatalyst was also determined by investigating the kinetics of the photocatalytic degradation of 4-nitrophenol under both UV-A …
