Description:
TiO 2 has been widely investigated due to its superior photocatalytic activity under ultraviolet irradiation among the photocatalyst materials. In this research, vanadium (V 3+ ) was doped into TiO 2 to enhance its light response under visible irradiation for wider application. Vanadium was introduced into TiO 2 lattice at various concentration respectively 0.3, 0.5, 0.7 and 0.9% using simple and fast sonochemical method. X-Ray Diffraction data show that vanadium doped TiO 2 crystallized in anatase phase with I 4 1 amd space group. X-Ray Diffraction pattern shifted to lower value of 2 θ due to vanadium dopant. It indicated that V 3+ was incorporated into anatase lattice. UV-Vis Diffuse Reflectance Spectra was revealed that the doped TiO 2 has lowered reflectance and enhanced absorption coefficient in visible region than undoped TiO 2 and commercial anatase TiO 2 .
