Abstract

Photocatalysis Photocatalysis is a complex process that involves multiple steps such as light absorption, electron-hole separation, and surface reactions. Introduction of cocatalysts is the most traditional approach to promoting or suppressing certain steps. However, this may come at the cost of lower overall stability caused by heterojunctions formed between the catalyst and cocatalyst(s). Jiang et al. designed a gallium-doped polymeric carbon nitride as a single photocatalyst that promotes the key steps of photocatalytic hydrogen production. The proposed photocatalyst displays excellent catalytic performance without the assistance of any cocatalyst, and indicates a promising direction toward the development of cocatalyst-free approaches for photocatalytic hydrogen production and other related processes.
