Abstract
- Designing approaches to synthesizing nanostructure photocatalysts is crucial to boosting applications in photocatalytic H<subscript>2</subscript> production. Herein, a Z-scheme p–n heterojunction for photocatalytic H<subscript>2</subscript> production was designed and constructed by decorating p-type CoP<subscript>3</subscript> quantum dots on n-type CdZnS nanorods. The flower-like CoP<subscript>3</subscript>/CdZnS nanorod assembly benefits from light absorption and full contact with the solution. An internal electric field forms at the interface of the p–n junction, which provides a Z-scheme charge transport path for efficient migration and separation of photogenerated charges. In result, the hydrogen production rate of the CoP<subscript>3</subscript>/CdZnS p–n junction is 33 times that of CdZnS. The study provided a novel approach to the synthesis of self-assembled nanostructures of quantum dots on nanorod assemblies that have important applications in photocatalysis for energy conversion.
