摘要
金属有机框架(MOFs)由于具有巨大的比表面积、超高的孔隙率、易修饰性和大量的活性位点及多孔结构等特性引起了研究人员的广泛关注,并应用于气体储存、传感器、催化剂等领域.然而,由于其自身固有缺陷,在上述领域实际应用中受到了限制.贵金属纳米材料具有优异的导电性、良好的催化性和独特的局部表面等离子体共振(LSPR)效应等特点,因此,近年来研究人员将贵金属纳米材料与MOFs进行多种形式的精妙组合构筑出纳米复合结构材料,由于二者"协同效应"产生一系列新颖特性,丰富了MOFs材料的应用领域,并显著提高了使用性能.本文综述了近年来Au、Ag、Pt等贵金属/MOFs纳米复合结构材料在催化、传感、生物医学和储氢等领域的应用进展,为制备新的纳米复合结构材料及开拓新的应用提供新思路.
Abstract
Metal-organic frameworks(MOFs)have attracted much attention due to their large specific surface area,high porosity,easy modification,large number of active sites and porous structures,and have been widely used in many fields,such as gas storage,sensors,catalysts and other fields.However,due to its inherent defects,their further practical applications in the above fields have been limited.Noble metal nanomaterials have excellent electrical conductivity,good catalysis and unique localized surface plasmon resonance(LSPR)effect.Therefore,researchers have delicately constructed nanocomposite structural materials by combining noble metal nano-materials and MOFs in various forms in recent years.Due to the synergistic effect of the two,a series of novel charac-teristics have been generated,enriching the application fields of MOFs materials and significantly improving their performance.In this paper,the application progress of Au,Ag,Pt and other noble metal/MOFs nanocomposite structural materials in catalysis,sensing,biomedicine and hydrogen storage in recent years is reviewed,which provides new ideas for preparing new nanocomposite materials and exploring new applications.
