ZnO–CdS@Cd Heterostructure for Effective Photocatalytic Hydrogen Generation

A novel heterostructure consists of a metal Cd core and a ZnO–CdS heterostructural shell, where ZnO nanoparticles are embedded in a CdS shell. Photocatalytic hydrogen evolution is greatly improved due to the metal Cd core, which provides a charge-carrier transport channel for enhancing the recombination of photoexcited electrons from ZnO and holes from CdS based on Z-scheme co-operation.
