摘　　要：MXenes作为一种新兴的二维层状过渡金属碳化物、氮化物和碳氮化合物,近年来被广泛应用于物理、化学、材料科学和纳米技术领域当中。MXenes制备过程中会不可避免地出现缺陷和—O,—OH,—F官能团,同时具备高的电导率和大的比表面积,使得MXenes具有良好的电子转移速率,可作为一种优良的电化学催化剂。本文综述了MXenes在电催化领域的研究进展,介绍了MXenes多种合成方法、不同掺杂类型的发展现状,重点讨论了其在电催化产氢、产氧、氧气还原、CO_(2)还原以及氮气还原过程中的应用及机理研究,并指出目前MXenes制备方法应朝着环境友好、形貌可控、难以氧化和高的可调节性方向发展,以便应用于不同的电催化反应中。MXenes,as a new 2D transition metal carbides/nitrides/carbonitrides,have wide potential application in physics,chemistry,material science and nanotechnology fields.Since MXenes inevitably possess defects and—O,—OH,—F terminal groups during the preparation,behaving high conductivity and large surface area,MXenes have a good electron transfer rate and can be used as an excellent electrochemical catalyst.In this review,the various synthesis methods and development of different doping types of MXenes were introduced.The application and mechanism of MXenes in electrocatalytic hydrogen production,oxygen production,oxygen reduction,CO_(2) reduction and nitrogen reduction processes were mainly discussed.It was pointed out that the preparation methods of MXenes should possess the characteristics of environmental friendliness,morphology controllability,the inoxidizability and high adjustability,meanwhile,different types of MXenes should be applied to different electrocatalytic reactions.
