Abstract

The p–n heterojunction of Cu2O/CdS have been prepared by a simple route of co-precipitation method. The results of SEM, TEM, XRD indicate that the surfaces of polyhedron Cu2O with different morphology are decorated by nanoparticle CdS. Compared with other structures under visible light, the Cu2O octahedra/CdS composites exhibit the highest photocatalytic property, which could be ascribed to that the unique heterojunction structure of the Cu2O/CdS could improve the photon-generated carrier separating and the Cu2O octahedral expose much more active surface than Cu2O cube.
