Abstract
Titanium dioxide has been considered one of the most promising photocatalytic materials due to its relatively low cost, chemical stability, and photo stability. In this work, CUO and WO<sub>3</sub> were loaded on anodic TiO<sub>2</sub> annotate and the photo electrochemical, photocatalytic and photo catalysts for hydrogen production activity were investigated. TiO<sub>2</sub> annotate was prepared by iodization method. CUO and WO<sub>3</sub> were loaded by wet impregnation method. The annealed samples were soaked in a mixture solution containing tungsten acid and Cu (NO<sub>3</sub>)<sub>2</sub> and then post-annealed to fabricate Cu-loaded TiO<sub>2</sub> annotate. The obtained samples were characterized by SEM, EDX, XRD and the photo electrochemical property, photocatalytic degradation of MB and photo catalysts for hydrogen production under UV illumination was measured and compared. The photocurrent (potential=1 V) of Cu-WO<sub>3</sub> loaded annotate is 1.41 times higher than that of unloaded annotate and is 1.15 times higher than that of pure WO3 loaded annotate. The hydrogen generation rate of Cu-WO3 loaded annotate is 1.42 times higher than that of unloaded annotate. After UV irradiation for 2 h, the degradation efficiency of MB for Cu-WO<sub>3</sub> loaded annotate is 1.12 times higher than that of pure WO<sub>3</sub> loaded sample.
