摘　　要：工业的快速发展导致了严重的有机水污染,对环境构成了严重威胁。MXene作为一种新型二维材料,由于优越的导电性、大的比表面积以及丰富的表面功能团等,受到广泛关注。然而MXene仍然存在纳米片堆积和催化过程中快速的电子-空穴复合等问题,这严重限制了其实际应用。通过将金属单原子锚定在MXene纳米片之间,形成MXene基单原子催化剂可以有效解决上述问题。本文综述了原始MXene和以MXene为基底的单原子催化剂的合成方法,并概述了MXene基单原子催化剂在去除水体有机污染物方面的研究进展,并对其未来的发展做出展望。The rapid development of industry has resulted in severe organic water pollution,posing serious threat to our environment.MXene,a novel two-dimensional(2D)material,has received widespread attention due to its excellent electrical conductivity,large specific surface area and abundant surface active sites.However,MXene still suffers from problems such as nanosheet stacking and rapid electron-hole complexation during catalysis,which seriously limit its practical applications.The above problems can be effectively solved by anchoring metal monoatoms between MXene nanosheets to form MXene-based single-atom catalysts.This paper reviews the synthesis method of pristine MXene and MXene-based single-atom catalysts and outlines the progress of research on MXene-based single-atom catalysts for the removal of organic pollutants from water bodies,and its development prospect is prospected.
