摘要

A novel supercapacitor electrode material based on heteroatom (N, O, P) doped mesoporous carbon microspheres (HMCMSs) was produced via a carbonization of highly cross-linked polyphosphazene microspheres (PMSs), with N, O, P acting as high efficient pore-forming agent. PMSs were synthesized through the polymerization reaction between melamine (MA) and hexachlorocyclotriphosphazene (HCCP). The high level of heteroatom atom of PMSs effectively afforde HMCMSs with high specific surface area (1854.1m2/g), united mesopore structure (pore width ~3nm), as well as high supercapacitor performance. HMCMSs based electrodes exhibited highest specific capacitance of 274 F/g in 6 M KOH aqueous electrolyte at a current density of 0.2 A/g, and excellent cycling durability which had 98.4% capacitance retained even after 2000 cycles. These animative consequences of HMCMSs based electrodes show them great potential in developing high- performance supercapacitors for actual application.
