摘要
综述了相较于工业制氢方法,光催化分解水制氢具有清洁无污染的优点。总结了研究者为了克服光催化分解水制氢过程中催化剂本身的缺点,提高光催化剂的析氢效率,对TiO 2光催化剂、过渡金属硫化物光催化剂以及g-C 3N 4光催化剂这三种类型的光催化剂的一些最新的改进方法,主要包括形态调控,元素掺杂,贵金属沉淀和复合光催化剂的合成,目前光催化分解水制氢依然受到析氢效率、成本因素以及繁杂的催化剂构建方法的制约。寻找价格合适的助催化剂,设计更加实用的构建光催化剂手段,得到具有更高析氢效率的光催化剂依旧是研究者需要重点关注的方向。
Compared with industrial hydrogen production methods,photocatalytic decomposition of water for hydrogen production has the advantages of clean and pollution-free.In order to overcome the shortcomings of catalysts in the process of photocatalytic decomposition of water to produce hydrogen and improve the hydrogen evolution efficiency of photocatalysts,researchers have summarized some of the latest improvement methods for three types of photocatalysts:TiO 2 photocatalyst,transition metal sulfide photocatalyst,and g-C 3N 4 photocatalyst,mainly including morphology regulation,element doping,noble metal precipitation,and the synthesis of composite photocatalysts.The photocatalytic decomposition of water to produce hydrogen is still limited by hydrogen evolution efficiency,cost factors,and complex catalyst construction methods.Finding suitable cocatalysts at an appropriate price,designing more practical means of constructing photocatalysts,and obtaining photocatalysts with higher hydrogen resolution efficiency are still the directions that researchers need to focus on.
