Abstract:Singlet oxygen(~1O2) is a kind of reactive oxygen species with mild oxidative potential, which is generated by peroxymonosulfate(PMS) activation over single-atom catalysts(SACs), showcasing excellent reactivity and selectivity toward electron-rich pollutants in water. This paper reviews the research progress of ~1O2 production by SACs/PMS systems toward water pollution abatement. The essential roles of ~1O2 in SACs are emphasized by summarizing the active centers of SACs, the reaction pathways of ~1O2, as well as the pollution abatement efficiencies. Moreover, the identification methods of ~1O2 and their existing problems are analyzed, while the future directions are outlooked. This review aims to provide guidance for the development of green and efficient SACs to exert the selective oxidation advantages of ~1O2.
