Research progress of photocatalytic catalysts for hydrogen production
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 shortcom-ings 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 im-provement methods for three types of photocatalysts:TiO2 photocatalyst,transition metal sulfide photocata-lyst,and g-C3N4 photocatalyst,mainly including morphology regulation,element doping,noble metal pre-cipitation,and the synthesis of composite photocatalysts.The photocatalytic decomposition of water to pro-duce hydrogen is still limited by hydrogen evolution efficiency,cost factors,and complex catalyst construc-tion methods.Finding suitable cocatalysts at an appropriate price,designing more practical means of con-structing photocatalysts,and obtaining photocatalysts with higher hydrogen resolution efficiency are still the directions that researchers need to focus on.
