Research Progress of Multi-component Metal Chalcogenides Catalysts and Photocatalytic Decomposition of Hydrogen Sulfide

以金属硫化物半导体为催化剂,以可见光为光源光催化分解硫化氢回收硫和氢气工艺,将太阳能利用、硫化氢的处理及制氢有机结合,极具发展前景。从三元金属硫化物、改性三元金属硫化物和多元金属硫化物3个方面综述了用于光催化分解硫化氢的多元金属硫化物,并指出了光催化分解硫化氢过程中存在的问题。

Photoeatalytic decomposition of hydrogen sulfide for evolution of hydrogen and recovery of sulfur under visible light irradiation lead to the realization of a green and sustainable energy system. Multi component-metal sulfides photocatalysts draw great attention for its high efficiency and band-gap controllable. Ternary chalcogenides, modified ternary chalcogenides and multi-component chalcogenides used as photocatalysts in the decomposition of hydrogen sulfide are reviewed. The problems should be settled in the future are summarized.
