Summary: | Photocatalytic overall water splitting is an ideal pathway to store solar energy, and produce clean and sustainable hydrogen fuel. However, exploring photocatalytic materials with high efficiency for overall water splitting remains a challenge. Herein, crystalline carbon nitride (CCN) was
in situ
grown on LaOCl to improve the performance for overall water splitting. Owing to the enhanced photogenerated carrier transfer by crystalline carbon nitride, and the promoted spatial separation of carriers
via
the built-in electric field between CCN and LaOCl, the optimized CCN/LaOCl composite catalyzes the decomposition of H

, respectively, prominently surpassing those of most of the reported carbon nitride-based photocatalysts. This work is anticipated to provide new perspectives for the rational design and preparation of CCN-based hybrid photocatalysts for solar water splitting. |
