Ⅰ 引言 光电子转移(ET)反应分解水受到广泛重视,虽然要实现大规模太阳能储存还有很多问题待解决;但近年进展很大。在光解硫化氢、光还原二氧化碳、光助电解水等方面也有进展。虽然光敏催化体系的成本降低、稳定性和循环数的提高也待解决,但众所关注的还是如何提高能量转化效率。没有较高的能量转化效率就难以和其他利用太阴能的途径相竞争。
I. INTRODUCTION Photodecomposition (ET) reactions are widely used to decompose water. Although there are still many problems to be solved for large-scale solar energy storage, progress has been greatly made in recent years. In the photolysis of hydrogen sulfide, photoreduction of carbon dioxide, light-assisted electrolysis of water, etc. also progress. Although the cost of the photo-catalytic system is reduced, the stability and the improvement of the number of cycles are to be solved, the concern is how to improve the energy conversion efficiency. Without higher energy conversion efficiency, it is difficult to compete with other ways of using solar energy.
