High nitrogen-doped carbon/Mn3O4 hybrids synthesized from nitrogen-rich coordination polymer particles as supercapacitor electrodes

摘要: High nitrogen-doped carbon/Mn3O4 composites were synthesized by annealing nitrogen-rich Mn-based coordination polymer particles, and investigated electron microscopy, X-ray diffraction, electrochemical experiments. To assess the performance of high hybrids as electrode materials in supercapacitors, cyclic voltammetry galvanostatic charging–discharging measurements are performed. charged discharged faster have higher capacitance than nanostructures with low nitrogen amounts other reported ones. The is 94% retained after 1000 cycles at a constant current. These improvements can be attributed to carbon matrix, which promotes fast Faradaic charging discharging Mn3O4 motifs. could promising candidate material for high-capacity, low-cost, environmentally friendly supercapacitors.
