摘要 半导体光电化学制氢是一种重要的、有前景的太阳能应用技术.其产氢效率主要取决于光生载流子的产生、分离和传输效率.深入理解光生载流子的动力学过程对于设计高效的太阳能产氢器件有重要的指导意义.光电化学和瞬态吸收光谱技术是研究光催化反应微观动力学和机理的强有力手段.本文介绍作者应用这些技术在半导体光电化学制氢方面所取得的部分最新研究结果,并对存在的问题和今后研究重点提出了一些看法. Semiconductor photoelectrochemical hydrogen production is an important and promising technology for utilizing solar energy. The efficiency of hydrogen production depends on the efficiencies of separation and transport of photo-generated carriers. A deep understanding of the behavior of these processes has guiding significance for designing efficient solar hydrogen device. Photoelectrochemical and transient absorption spectroscopy methods are powerful for studying the microscopic dynamics and mechanism ofphotocatalytic reaction. This review describes the latest results regarding the semiconductor photoelectrochemical hydrogen production obtained by these methods. The problems are indicated and future research priorities in this field are proposed.
