Research progress in optimization of transition metal sulfide catalysts and hydrogen production from photocatalytic water splitting
Transition metal sulfide catalysts with abundant reserves and low prices exhibit high activity for hydrogen production from photocatalytic water splitting and are ideal choices to replace precious metal platinum catalysts.The preparation methods,structural morphologies and hydrogen production rates of transition metal sulfide catalysts for hydrogen production from photocatalytic water splitting were reviewed.Strategies for improving the efficiency of hydrogen production from photocatalytic water splitting by transition metal sulfide catalysts and their composite catalysts were discussed,including expanding the light absorption range,enhancing the separation of photogenerated electron-hole pairs and promoting catalyst surface reactions,to prepare more efficient transition metal sulfide catalysts that meet commercial requirements.At last,the future research trends in the field of hydrogen production from photocatalytic water splitting by transition metal sulfide catalysts were prospected.
