Swapping ions: Nanoporous CdxZn1−xS nanosheets with single-crystal-like structure, good structural stability, and tunable pore size and composition have been successfully fabricated by the cation-exchange reaction of prepared ZnS–amine hybrid nanosheets with Cd2+ cations (see picture). The porous CdxZn1−xS nanosheets are highly active for photocatalytic H2 evolution from water splitting.
