半导体光催化全分解水的最新研究进展

Recent Research Progress on Overall Water Splitting by Semiconductor Photocatalysts

从半导体光催化剂全分解水反应原理出发,介绍了近年来新开发的无机半导体光催化剂,如钽酸盐半导体,Ge基半导体、Ga基半导体,层状金属氧化物,具有d0、d10电子构型的半导体和Z型反应体系,分析了光催化效率的影响因素,并对未来做出了展望。

Starting from the principle of semiconductor photocatalysts for overall water splitting,the new semi- conductor photocatalysts like tantalates, Ge or Ga based semiconductors, layered structure metal oxides, semiconduc- tors with do or d10 electronic configuration and Z-scheme photosystem for overall water splitting in recent years, are in- troduced. The affecting factors of photocatalytic efficiency are also discussed and an outlook for future research is pro- posed.
