Recent Progress of Two-dimensional Metal-organic Framework Nanosheets for Supercapacitor and Electrocatalysis Applications

二维金属有机框架(2D MOF)纳米片具有丰富且易暴露的表面活性位点、高度有序的孔结构以及多样且可调的化学成分,在电化学能量存储与转化中有利于降低反应电位,提高扩散速率和反应速率.关于2DMOF应用于电化学存储与转化的研究已有大量报道.本文综合评述了近几年2D MOF的合成进展及其在超电容(SC)、析氧反应(OER)、析氢反应(HER)、氧还原反应(ORR)和二氧化碳还原反应(CRR)的应用,并对2D MOF作为电催化材料的研究现状和发展前景进行了总结与展望.

Two-dimensional metal-organic framework(2D MOF)nanosheets attract increasing research attention due to their unique properties originating from their abundant and easily exposed surface active sites,highly ordered pore structure,as well as varied and tunable chemical composition.These structural advantages help reduce the reaction potential and increase the diffusion rate and reaction rate in electrochemical energy storage and conversion.In this review,we first summarize the synthetic strategies of 2D MOF,and then an overview of applications of 2D MOF in supercapacitance(SC),oxygen evolution reaction(OER),oxygen reduction reaction(ORR),hydrogen evolution reaction(HER),carbon dioxide reduction reaction(CRR)is given.Finally,the status quo and prospects for the research of 2D MOF nanosheets are presented and discussed.
