摘要
直接利用太阳能光解水制氢是解决世界能源危机的重要途径之一 ,本文概述了利用光催化技术催化分解水制氢的反应机理 ,介绍了几种现已研究的光催化剂及提高其光化学反应活性的途径 。
Hydrogen production directly from water by solar energy on semi conductor photocatalysts is one of the important ways to solve the world energy crisis. The mechanisms of the photocatalytic decomposition of water into hydrogen and oxygen are summanzed in this paper. Some photocatalysts used currently and the ways of improving their activities are introduced, and the future study is previewed.
