Rational design of CdS@ZnO core-shell structure via atomic layer deposition for drastically enhanced photocatalytic H2 evolution with excellent photostability

TLDR: In this paper, an atomic layer deposition (ALD) technology was used to fabricate a new class of CdS@ZnO core-shell heterostructure, which not only allows the light to be absorbed by Cdc core, but also provides an intimate heterojunction interface between ZnO shell and CcS core.
