摘要
近年来,研究者提出了一种新的S-型异质结光催化剂。S-型异质结光催化剂在光生电子空穴对的有效分离、无用电子空穴的复合、载流子的有效分离、保留强氧化-还原活性位点等方面有着显著的优点。综述了近年来,S-型异质结光催化剂的反应机理、制备方法,以及在水分解制氢、CO_(2)还原、污染物的降解、灭菌等应用方面的研究进展,提出了S-型光催化体系的发展前景和面临的挑战。
In recent years,researchers have proposed a new S-scheme heterojunction photocatalyst,which has distinct advantages in the effective separation of photogenerated electron-hole pairs,recombination of useless electrons and holes,high separation efficiency of charge carriers,and retention of strong oxidation reduction active sites.In this paper,the reaction mechanism and preparation method of S-scheme heterojunction photocatalyst and the research progress of its application in water decomposition to produce hydrogen,CO_(2) reduction,and the degradation and sterilization of pollutants have been summarized.Finally,prospects and challenges for the development of S-scheme photocatalytic systems are presented.
