摘　　要：双金属有机骨架及其衍生物一方面具有单金属有机骨架孔道丰富、比表面积大、结构可调、活性位点丰富等特点,另一方面具有双组分与多孔结构之间的协同效应,因而受到了研究人员的密切关注,在储能、催化、分离、传感器、医药、气体存储等领域广泛应用。和单金属MOFs类似,双金属MOFs的导电性不佳、结构易坍塌,这极大地限制了其在电化学储能中的应用。通过对双金属MOFs进行热处理,易得到分布均匀的多孔碳@双金属氧化物/硫化物/磷化物/硒化物等衍生物,不仅保持了独特的多孔结构,而且提高了材料的导电性和结构稳定性,有利于在电化学储能中的应用。因此,本文从双金属MOFs中的主要金属离子入手,综述了双金属MOFs及其衍生物用于超级电容器、锂离子电池、钠离子电池、金属空气电池等电化学储能器件的最新应用进展。在此基础上,总结了双金属MOFs在电化学储能应用中的优势,并对其制备、作用机理和后处理研究提出了建议。Bimetallic organic frameworks and their derivatives have the characteristics of rich pore structure,large specific surface area,adjustable structure,abundant active sites,as well as the synergistic effect between bi-component and porous structure,so they are paid close attention to by researchers and widely used in electrochemical energy storage,catalysis,separation,sensors,medicine,gas storage and other fields.Just as monometallic organic frameworks,the poor conductivity and collapsible structure of bimetallic organic frameworks greatly limit their applications in electrochemical energy storage.It is through heat treatment of bimetallic organic frameworks that porous carbon@bimetallic oxide/sulfide/phosphide/selenide derivatives with uniform distribution,which not only keep rich pore structure,but also have improved conductivity and structural stability,being conducive to the application in the field of electrochemical energy storage are obtained.Therefore,in the view of the main metal ions in the bimetallic organic frameworks,this research reviewes the latest progress of the organic frameworks and their derivatives in electrochemical energy storage devices such as supercapacitors,lithium ion batteries,sodium ion batteries,and metal-air batteries,respectively.On this basis,the advantages of bimetallic MOFs in the application of electrochemical energy storage are summarized,and suggestions on its preparation,mechanism and post-treatment are put forward.
