Abstract
En 中文
Photocatalysts with hollow structure have obvious advantages in photocatalytic hydrogen production. Herein, CoP was modified on the surface of CdS by sacrificial template method to prepare CdS/CoP composite photocatalyst with hollow structures. Compared with pure CdS, CdS/CoP nanocage has improved photocatalytic hydrogen production performance due to its hollow structure, excellent light absorption capacity, and electronhole pair separation and transfer efficiency. The hydrogen production rate of CdS/CoP can reach to 15.74 mmol g(-1) h(-1), which is about 9 times than that of pure CdS. It is found that the formation of a p-n heterojunction between CdS and CoP is the key factor to improve the photocatalytic performance of the composites. This study provides a simple strategy for the construction of more hollow nanocomposite catalysts with excellent photocatalytic performance.
