چکیده:

TiO2/Sb nano photocatalyst was prepared by Titanium Tetra isoPropoxide (TTiP) and dopant Sb3+ ions via a sol-gelprocess. The structure and properties of the nano catalyst were characterized by Fourier Transform Infra Redspectroscopy (FT-IR), Scanning Electron Microscopy (SEM) equipped with EDX spectroscopy and the crystallinestructural properties were determined by X-Ray Diffraction (XRD) technique. The photocatalytic activities wereevaluated by photocatalytic degradation of methyl orange (MO) solution under UV irradiation and the photocatalyticproperties were compared with TiO2 in Photochemical (P) and coupled systems of Electro Photochemical (EP),Photochemical in the presence of Air (PA) and Electro Photochemical in the presence of Air (EPA). The resultsshowed that TiO2/Sb nano photocatalyst had better photocatalytic activity comparing with TiO2 and the coupled systemof electro photochemical with air showed the best degradation ability.
