A “uniform” heterogeneous photocatalyst: integrated p–n type CuInS2/NaInS2 nanosheets by partial ion exchange reaction for efficient H2 evolution†
Abstract
Single-crystalline-like P–N type CuInS2/NaInS2 heterogeneous nanosheets were synthesized by partial cation exchange reaction and show highly improved photocatalytic H2 evolution activity attributed to the increased efficiency of interfacial charge transfer.
