Superior activity of the CuS–TiO2/Pt hybrid nanostructure towards visible light induced hydrogen production

Abstract

A CuS–TiO2 hybrid nanostructure has been synthesized and employed for photocatalytic hydrogen production under UV-Vis light using Na2S and Na2SO3 as the sacrificial agents. The remarkable hydrogen production recorded for the CuS–TiO2 heterostructure was 458 μmol h−1 g−1 and for CuS–TiO2/Pt was 746 μmol h−1 g−1. The corresponding apparent quantum yield values are 1.01% and 1.55%. The addition of Pt to the hybrid structure acts as a metallic sandwich between two semiconductors CuS and TiO2 which assist in charge separation.
