MnCo2O4/g-C3N4 composite material preparation and its capacitance performance

MnCo 2 O 4 /g-C 3 N 4 composite material was synthesized by the hydrothermal method, compared with MnCo 2 O 4 without g-C 3 N 4 , it has excellent electrochemical performance. The composite material can reach a specific capacitance of 350 Fg[Formula: see text] at 1 Ag[Formula: see text]. The capacity retention rate is 96% after 1000 cycles at the rate of 2 Ag[Formula: see text]. Experiments show that g-C 3 N 4 can effectively disperse and...
