Abstract:

Photocatalytic decomposition of water to hydrogen is a green way to effectively convert solar energy to hydrogen energy.Among them,semiconductor core-shell photocatalyst shows excellent performance in solar decomposition of water to hydrogen.From the perspective of semiconductor material modification,the latest research progress of hydrogen production from water decomposition by semiconductor core-shell photocatalyst at home and abroad was reviewed and commented.The basic principles and modification effects of common oxides,nitrogen oxides,nitrides and sulfide core-shell semiconductor photocatalysts in hydrogen production from water decomposition were emphatically expounded.The effects of modification methods such as doping ions,constructing heterojunctions and loading co-catalysts on changing the band gap of photocatalyst,reducing the recombination probability of photogenerated carriers,accelerating the transmission rate of photogenerated charges and increasing the active sites of hydrogen production were analyzed.It was proposed that the future research direction of hydrogen production from water decomposition photocatalyst could be further developed for crystal-plane-dependent nano-composite photocatalytic materials,auxiliary-modified photocatalytic materials and new photocatalytic semiconductor materials.
