单原子催化剂中M-Nx-C活性位点活化过硫酸盐产生非自由基途径的作用与构建方法
Methods for the formation of M-Nx-C active sites on single-atom catalysts and their role in persulfate activation by non-radical paths
摘要
Abstract
In recent years,numer-ous single-atom catalysts(SACs)have been synthesized to activate persulfate(PS)by a non-radical pathway because of its high se-lectivity,and activity for the cata-lyst.Metal-nitrogen-carbon(M-Nx-C)has been identified as the key active site in SACs.Although methods for preparing SACs have been extensively reported,a systematic summary of the direct construction of M-Nx-C,espe-cially unconventional metal-nitrogen-carbon(UM-Nx-C,x≠4),on SACs for PS non-radical activation has still not been reported.The role of the M-Nx-C active sites on PS non-radical activation is discussed and methods for the formation of M-Nx-C and UM-Nx-C active sites in SACs and the effect of catalyst carriers such as carbon nitride(g-C3N4),MOFs,COFs,and other car-bon materials are reviewed.Direct and indirect methods,especially for UM-Nx-C active site formation,are also elaborated.Factors affecting the formation of a M-Nx-C active site on SACs are also discussed.Prospects for the use of M-Nx-C active sites for the non-radical activation of PS by SACs to remove organic contaminants from wastewater are evaluated.关键词
