摘　　要：Photocatalytic water splitting using natural solar light is considered as a sustainable approach to generate H_(2) and O_(2).While H_(2) has high market value,the by-product of water splitting,oxygen,is less valuable.To make H_(2) produced by means of photocatalysis more economically competitive to that generated from methane,its generation is studied together with synthesis of organic compounds that have higher market value.This review summarizes and analyzes critically dehydrogenation reactions that were developed since 1980s.Photocatalytic dehydrogenation reactions are classified and the results are collected in the online database.Performance of homogeneous and heterogenous photocatalysts in dehydrogenation reactions,such as yield rates of organic products on analytical and preparative scales,and quantum efficiencies are compared.Current limitations of the existing methods and photocatalytic systems are identified and directions for the future developments are outlined.利用自然太阳光进行光催化水分解被认为是一种可持续的生产H_(2)和O_(2)方法.虽然H_(2)具有很高的市场价值,但水分解的副产品O_(2)的价值较低.为了使光催化制氢在经济性上优于甲烷制氢,研究者通常将氢气的生成与高附加值有机物的合成相结合进行研究.本文对20世纪80年代以来发展起来的脱氢反应进行了批判性总结和分析,对光催化脱氢反应进行了系统性分类,并将结果收录于在线数据库中.该数据库对均相和非均相光催化剂在脱氢反应中的性能(如分析及制备规模下有机物的产率及量子效率)进行了比较,指出了现有方法和光催化系统的局限,并展望了未来的发展方向.
