摘要	A Cu2O/Pt/BiVO4 heterojunction was prepared by successively depositing Pt and Cu2O nanoparticles on {010} facets of BiVO4, showing much higher photocatalytic activity in hydrogen evolution than that constructed by random deposition of Cu2O on all facets of BiVO4 particles. Photoluminescence spectroscopy revealed that the facet-selective Cu2O/Pt/BiVO4 arrays effectively promoted charge separation of the BiVO4 host. A band alignment was consequently presented to illustrate the interface charge flow in the heterojunction. This work demonstrates the roles that facets played in semiconductor heterojunctions applied to photocatalytic reactions.
