Abstract: The poor electrical conductivity of metal organic frameworks (MOF) with rich porous structures limits their practical application in supercapacitor electrode materials. With MOF crystalline material and polypyrrole (PPy) chains embedded in the 3D network structure of graphene (GE) aerogel, 3D hierarchical porous structure can be successfully constructed. Simultaneously, high level and stable doping of conductive PPy, which can further improve the supercapacitive performance of the composite aerogel. Co-MOF, Ni-MOF and bimetallic CoNi-MOF were obtained by hydrothermal method with Co(NO₃)₂·6H₂O and Ni(NO₃)₂·6H₂O as metal source and trimesic acid (H₃BTC) as organic ligand. Then MOF/PPy/GE ternary composite aerogels were prepared with MOF crystal material pyrrole (Py) and graphene oxide (GO) by one-step hydrothermal method. The composite morphology, chemical structure, and doping structures were characterized by SEM, TEM, FTIR, XRD, Raman and XPS techniques. The results show that the bimetallic CoNi-MOF material is more easily embedded in the three-dimensional network structure of the composite aerogel, and could effectively suppress the accumulation of GE layers by constructing a stable three-dimensional porous network structure together with graphene layers and PPy conjugated long chains. The electrochemical test results show that the specific capacitance of the CoNi-MOF/GE/PPy composite aerogel (GPMOF-CoNi) can reach 447 F/g, and the capacitance retention rate of 10000 cycles is up to 97%, showing good supercapacitive performance.
