PREPARATION AND CHARACTERIZATION OF TITANIUM DIOXIDE CODOPING WITH V AND Pt

WU Zun-yi(College of Food Science,Biotechnology and Environmental Engineering,Zhejiang Gongshang University,Hangzhou 310035,China)  
Using Ti(OBu)_4,H_2PtCl_6 and(NH_4)_3VO_4 as raw materials,V-TiO_2,Pt-TiO_2 and V-Pt-TiO_2 were prepared via Sol-gel method.The catalysts were characterized by XRD,SEM and UV-Vis spectra.Activities of the photocatalysts were evaluated by photodegradation of Cl_3CCOOH.The result shows that the V and Pt do not change the morphology of the titanium.But they can effect the visage and the UV-Vis spectra of the titanium.Activities of the photocatalysts are obviously enhanced when titanium were codoped with V and Pt.The reasons are discussed simply.
