过渡金属有机框架结构构件及电解水研究进展

Metal-organic framework based on transition metal and their application in electrocatalysis

金属有机框架(MOF)材料由于其比表面积大、孔隙率高、结构可调控和单分散的活性中心等特性,在吸附分离、气体储存和电催化等领域具有巨大的应用前景,其中,在催化领域的应用尤为突出。目前,利用传统方法所制备的MOF虽然含有具有催化活性的金属,但是MOF中的金属位点通常和有机配体相结合,无法很好的暴露出来,导致在催化过程中表现出来的活性很低。因此大部分关于MOF催化性能的研究,主要集中于MOF与纳米金属粒子相结合的方式。文中总结分析了近年来以不同合成方法制备的零维、一维和二维MOF结构,并对基于过渡金属构建的MOFs材料在电催化水分解的应用进展和面临的挑战进行了分析讨论。

Metal-organic framework(MOF)materials have great application prospects in the fields of adsorption and separation,gas storage and electrocatalysis due to their large specific surface area,high porosity,adjustable structure and monodispersed active centers.Among them,the application in the field of catalysis is particularly outstanding.At present,the MOF prepared by the traditional method contains metal with catalytic activity.However,binding to the organic ligand usually,metal sites that cannot be well exposed to the active metal,cause the loss of catalytic performance in practical reaction processes.Therefore,most of the studies on the catalytic performance of MOF mainly have focused on combining MOF and nano-metal particles.This paper summarized zero-dimensional,one-dimensional and two-dimensional MOF structures prepared by different synthetic methods,and discussed the application progress and challenges of MOFs based on transition metal in electrocatalytic water splitting.
