MnO2 microsphere/graphene aerogel

MnO2 microsphere/graphene aerogel;MnO2 microsphere/GO from ruixi.Graphite oxide was prepared using an improved Hummers method. The prepared MnO2 microspheres were evenly dispersed in the graphene oxide dispersion, and the MnO2 microspheres/graphene aerogel composite (MnO2/GA) was self-assembled through hydrothermal reaction. Its phase, morphology, and specific surface area were characterized, and its electrochemical properties were tested. The results showed that the MnO2 microspheres were embedded and coated in graphene sheets, and at a current density of 0.5 A·g~(-1), The specific capacitance of MnO2/GA is 175.5 F·g~(-1), which is higher than the specific capacitance of MnO2 (78.4 F·g~(-1)), and after 1 000 cycles, MnO2/GA has more stable cycle performance .
