基于金属有机框架结构衍生多孔碳材料制备及电催化进展

Progress on preparation and electrocatalysis of porous carbon materials derived from MOFs

金属有机框架结构(MOFs)是指通过配位键由金属离子或团簇和有机配体自组装形成的多孔无机-有机杂化材料。MOFs材料具有丰富的孔结构分布、较大的比表面积、多样的结构与功能、大量的金属活性位点等特点,被广泛应用于催化、传感、气体吸附、能源储存。然而,由于大多数MOFs材料在强酸碱环境中不稳定,导电性较差,特别是将MOFs直接用作电催化剂时的催化性能不高。近年来,大量研究表明通过将不同种类的MOFs作为模板制备新颖的多孔碳纳米催化剂,表现出了高电催化活性、优异的稳定性等优势。综述了MOFs及其衍生多孔碳材料的类型和制备方法,并介绍了MOFs衍生多孔碳材料在电催化方面的一些应用。

Metal-Organic Frameworks(MOFs)refer to porous inorganic-organic hybrid materials formed by self-assembly of metal ions or clusters and organic ligands through coordination bonds.MOFs materials have the characteristics of rich pore structure distribution,large specific surface area,diverse structures and functions,and a large number of metal active sites.They are widely used in catalysis,sensing,gas adsorption,and energy storage.However,since most MOFs are unstable in strong acid and alkali environments and have poor electrical conductivity,especially when MOFs are directly used as electrocatalysts,their catalytic performance is poor.In recent years,many studies have found that by using different kinds of MOFs as templates to prepare novel porous carbon nanocatalysts,it exhibits the advantages of high electrocatalytic activity and excellent stability.The types and preparation methods of MOFs and their derived porous carbon materials were reviewed,and introduced some applications of MOFs derived porous carbon materials in electrochemical catalysis.
