Abstract:

Electrode material is a key component of supercapacitors (SCs). As a porous material, metal-organic frameworks (MOFs) have attracted much attention in the field of SCs electrode materials due to their high specific surface area, controllable structure, and adjustable pore size. The low conductivity and stability of MOFs are still the main challenges in practical applications. MOF composite materials are a type of composite materials composed of MOFs and one or more different materials. They can effectively combine the advantages of MOFs with the advantages of other functional materials, such as excellent electrical conductivity and unique electrochemical properties. Therefore, MOF composite materials can achieve high reversible capacity and excellent cycle performance, overcome the shortcomings of MOFs materials, and have broad application prospects in the field of SCs electrode materials. According to the dimensional classification of the materials combined with MOFs, they can be divided into four types of composite materials: 0D, 1D, 2D, and 3D MOFs. The composition and synthesis methods of these four types of composite materials are reviewed. The application of MOF composite materials in the field of SCs is systematically introduced. Furthermore, its development prospects are prospected.

摘要：

电极材料是超级电容器（SCs）的关键部件，金属有机框架（MOFs）作为一种多孔材料，由于其具有比表面积大、结构可控、孔径可调等优点在SCs电极材料领域得到诸多关注，而MOFs的低导电性和稳定性仍然是实际应用中的主要挑战。MOF复合材料是一类由MOFs与一种或多种不同材料组成的复合材料，它可以有效地结合MOFs和其他功能材料的优势，例如优良的导电性和独特的电化学性质等。因此，MOF复合材料可以实现高可逆容量和优良的循环性能，克服MOFs材料的缺点，在超级电容器电极材料领域具有广阔的应用前景。根据与MOFs复合的材料维度分类，可分为0D、1D、2D和3D MOFs四类复合材料，重点综述了这四类复合材料的组成及合成方法，并系统介绍了MOF复合材料的SCs应用，对其发展前景进行展望。
