Abstract:

Photocatalytic technology has outstanding advantages such as simple synthesis process,easy control of reaction conditions,full utilization of solar energy,and no secondary pollution.It has broad application prospects in addressing environmental pollution problems and alleviating global energy shortages.However,due to the low transfer and separation efficiency of photo generated carriers,the actual improvement of photochemical conversion efficiency is limited.The emerging S-tpye heterojunction photocatalysts have received widespread attention and research in the fields of solar fuel preparation and environmental governance due to their effective transfer and separation of photo generated carriers in space and their strong redox power.The development history of heterojunction photocatalysts,the basic principles of S-tpye heterojunctions,and their applications in various fields were reviewed.Finally,the outstanding advantages of S-tpye heterojunction photocatalysts were summarized,and the development prospects and challenges faced by S-tpye heterojunction photocatalysts were proposed,providing ideas and references for the development of new heterojunction photocatalysts with high photocatalytic activity.

Key words: S-type heterojunction, photocatalysis, hydrogen evolution, carbon dioxide reduction, degradation
