摘　　要：近年来,生态污染和能源稀缺问题影响着人类的生活,绿色、低碳的光、电催化技术引起了人们的广泛关注。基于半导体的光、电催化技术在合成氨应用上极具前景,而由于单一半导体存在载流子分离效率低、容易复合等缺点,因此寻找能够提升固氮催化剂性能的助催化剂成为关键。二维过渡金属碳化物/氮化物/碳氮化物MXene,在光、电催化合成氨领域具有广阔的应用前景。MXene具有良好的亲水性、大的比表面积、优异的导电性和丰富的高效催化N2还原的活性位点,是光、电催化固氮材料的理想选择。本文主要综述了MXene及复合材料的制备及其在光电催化合成氨领域的进展。首先,简要总结了MXene的结构特点和MXene及其复合物的制备策略。其次,重点介绍了MXene基复合催化剂在光、电催化合成氨方面的性能研究。最后对MXene基复合材料的发展方向进行探讨与展望。In recent years,the problems of environmental pollution and energy scarcity have affected human life,and green and low-carbon photocatalytic and electrocatalytic technologies have attracted widespread attention.Semiconductor-based photocatalytic and electrocatalytic technologies are very promising for ammonia synthesis applications.Since single semiconductors suffer from the disadvantages of low carrier separation efficiency and easy compounding,it is crucial to find co-catalysts that can enhance the performance of nitrogen fixation catalysts.Two-dimensional transition metal carbide/nitride/carbon nitride MXene,which has a promising application in photo-and electrocatalytic ammonia synthesis,is ideal for photo-and electrocatalytic nitrogen fixation owing to their good hydrophilicity,large specific surface area,excellent electrical conductivity and abundance of active sites for efficient catalysis of N2 reduction.This paper mainly reviews the preparation of MXene and its composites and their progress in the field of photoelectrocatalytic ammonia synthesis.Firstly,the structural features of MXene and the preparation strategies of MXene and its complexes are briefly summarised.Secondly,the performance study of MXene-based composite catalysts for photo-and electrocatalytic ammonia synthesis is highlighted.Finally,the development direction of MXene-based composites is discussed and prospected.
