摘要
基于可再生能源的电解水技术是生产“绿氢”的主要方法但受限于高电耗以及由此产生的高电力成本,电解水技术在大规模推广应用方面仍面临困难。降低电耗的途径在于开发高性能的电催化剂。MXenes是一种碳化物、氮化物和碳氮化物组成的二维材料,具有高导电性、大比表面积、高机械强度和优异的亲水性,是电催化剂的理想载体,被广泛应用于电解水制氢领域的研究。首先介绍了MXenes的基本组成与结构特征,其次总结分析了MXenes直接用于电解水制氢方面的研究成果,并阐述了其作为载体材料锚定高活性物质用于析氢和析氧反应的应用和进展,最后总结并展望了MXenes材料未来的发展前景。
Renewable energy-based water electrolysis is the main method of producing“green hydrogen”,but it still faces difficulties in large-scale application due to high power consumption and the resulting high cost of electricity.The way to reduce power consumption lies in the development of highperformance electrocatalysts.MXenes is a two-dimensional material composed of carbides,nitrides and carbon-nitrides with high electrical conductivity,large specific surface area,high mechanical strength and excellent hydrophilicity,which is an ideal carrier for electrocatalysts and has been widely used in the research in the field of hydrogen production by electrolysis of water.This paper firstly introduces the basic composition and structural characteristics of MXenes,summarizes and analyzes the research results on the direct use of MXenes in electrolysis of water for hydrogen production,and describes the application and progress of its use as a carrier material to anchor highly active substances for hydrogen and oxygen evolution reaction,and finally summarizes and looks forward to the future development prospects of MXenes materials.
