Evaluating the efficiency of nano-sized Cu doped TiO2/ZnO photocatalyst under visible light irradiation

A visible light responsive photocatalyst, nano-sized copper doped TiO2/ZnO, was synthesized by sol gel method. It was characterized in terms of thermal stability, crystalline phase, crystal size, morphology, surface area, UV–Vis DRS and band gap. The results showed that the synergistic effect of cop...
