英文摘要： Porous metal-organic frameworks (MOFs) possess promising application future in a new class of energy storage materials with enormous internal surface areas, adjustable pore sizes, and abundant topological framework; however, the application research of MOFs as supercapacitor electrode materials is in the just beginning stage. This proposal is expected to construct series of novel porous MOFs base on rigid pyridine carboxylic acid ligands with different size and variable-valence transition metal ions with specific function and configuration under the control of synthetic condition. We will investigate the porosity and capacitive performance of the target MOFs materials with the influences on performance from the pore size, specific surface area and metal ions; the purpose is to discloses the inner relationship among design, synthesis and capacitive performance of materials. Further study is to select the materials with high specific capacitance and good cycling stability and evaluate the basis for its application. After the implementation of this project, we anticipate to further develop application of MOFs materials and lay a foundation for the development of new energy storage materials.
