摘　　要：硫化氢(H2S)作为一种剧毒、恶臭的强腐蚀性气体,广泛来源于人类活动和自然界,对动植物生存和环境都具有较大的危害。光催化分解H2S制氢是一种理想的H2S处理技术,可以同时实现H2S的转移和清洁能源氢气的产生。近年来,金属硫化物由于其优异的可见光响应、恰当的能带结构和对H2S有高的稳定性,因此被广泛地应用于光催化分解H2S制氢。本文对近年来国内外金属硫化物驱动H2S资源化利用制氢领域取得的重要进展进行了概述和总结,探讨了不同反应媒介下光催化分解H2S制氢机制;特别关注了一些为实现高效稳定光催化H2S资源化利用制氢的优异调控策略;最后,对H2S资源化利用的挑战和前景进行了展望。Hydrogen sulfide(H2S),owing to the extremely toxic,malodorous and corrosive nature,is a detrimental and undesirable environmental pollutant widely generated in the petrochemical industry.How to handle H2S effectively and convert it into highly-valued products is vital.Photocatalysis is one of the most ideal routes to realize the resource utilization of H2S.Recently,metal sulphides are widely used as desirable photocatalysts for H2 production from waste H2S due to their remarkable visible-light response,proper band structure and strong resistance against H2S poisoning.Here,we summarize the current status,and challenges of this field.The photocatalytic H2S splitting mechanism are overviewed in different reaction medium.Particularly,promising strategies for highly efficient photocatalytic conversion of H2S are systematically discussed,which is aimed to inspire researchers interested in this field.Finally,some challenges in the H2S splitting process and their future research directions are outlined.
