CuO/CuSCN valence state heterojunctions with visible light enhanced and ultraviolet light restrained photocatalytic activity.

CuSCN is applied, for the first time, in a photocatalytic system to form CuO/CuSCN valence state heterojunctions, which exhibited enhanced visible light driven photocatalytic activity and, surprisingly, ultraviolet light restrained activity. Proper migration of photo-generated carriers is proposed to explain the photocatalytic process.
