Abstract
The heterojunction in photocatalysis establishes an internal electric field between the semiconductors, which is one of the effective methods for enhancing the separation of photogenerated carriers of semiconductors. Herein, a strategy is rationally proposed, which is performed in situ to transform the hybrid photocatalyst composed of the Ni–Co Prussian blue analogue (PBA) and CdS (CP) into another more active hybrid photocatalyst consisting of NiS and CdS (CN) during photocatalysis in the sulfur sacrificial reagent. The coupled component on the n-type CdS is converted from an n-type Ni–Co PBA to another p-type NiS during the process, thus constructing a p–n heterojunction and achieving a good photocatalytic…
