摘要:

金属有机框架(MOFs)材料因其大的比表面积、可调控的孔道结构和丰富的活性位点引起了国内外学者们的广泛关注。近年来MOFs基材料广泛应用于能量储存与转化领域,但大多数MOFs基材料的低稳定性和低导电性等缺陷限制了其实际应用。通过对MOFs基材料进行改性,如采用共轭度高的有机配体以增加MOFs材料的稳定性,或MOFs衍生物以提高其氧化还原活性位点和导电性,从而达到提高MOFs基电极材料的电化学性能。主要介绍了原始MOFs及其衍生材料如碳材料、金属氧化物、金属硫化物、金属氢氧化物和金属磷化物等在超级电容器电极材料中的最新研究进展。研究表明,多金属MOFs材料或多金属MOFs衍生物有利于提高电极材料的电化学性能,而导电MOFs材料或MOFs衍生物中的碳材料有利于提高电极材料的导电性。最后对MOFs基电极材料在电化学储能领域中的研究做出了展望,指出MOFs基材料的形貌、组分和导电性是未来研究的发展方向。

Abstract:

Metal-organic frameworks(MOFs) have attracted extensive attention due to their large specific surface areas,controllable pore structures and abundant active sites.Recently,MOFs-based materials were widely used in the field of ener-gy storage and conversion; however,the low stability and low conductivity of most MOFs-based materials limit their practical applications.By modifying MOFs based materials,such as the use of high conjugated organic ligands could increase the stabi-lity of MOFs materials or MOFs derivatives could improve their redox active sites and electrical conductivity,thus,the elec-trochemical performances of MOFs-based electrode materials can be improved.In this review,we mainly introduce progress of the pristine MOFs and MOFs derivatives including carbon materials,metal oxides,metal sulfides,metal hydroxide and metal phosphide, etc.in the field of supercapacitor.The results show that multi-metallic MOFs or their derivatives are beneficial to improve the electrochemical performances,the conductive MOFs and the carbon materials,which are derived from MOFs materials,are beneficial to improve the electrical conductivity of electrode materials.Finally, the outlook and prospect of MOFs-based electrode materials for electrochemical energy storage are also point out.The morphology, components and conductivity of the electrode materials are research develop direction in the future work.
