ResumoZnO surfaces are mainly covered by two polar facets and six nonpolar facets. Due to the unique advantage of polar facets in promoting interface charge carrier transfer in ZnO–CdS heterostructures, the hydrogen evolution rate over ZnO disk–CdS nanoparticle heterostuctures is 2.8 times that of the ZnO rod–CdS nanoparticle one.
