A series of heteroatom doped ordered mesoporous carbons(HOMCs)such as ordered mesoporous carbon(OMC),nitrogen doped ordered mesoporous carbons(NOMC),phosphorus doped ordered mesoporous carbons(POMCs),and nitrogen and phosphorus co-doped ordered mesoporous carbon(NPOMC)were synthesized via a chemical vapor deposition nanocasting(CVD nanocasting)route using SBA-15 as the template at 800 ℃ for high-performance supercapacitor.The formation of the template and HOMCs were confirmed by various physicochemical characterization techniques such as XRD,RAMAN,BET,SEM-EDAX,HR-TEM and XPS.The magnetic properties of prepared HOMCs were measured.Also,the electrochemical properties of HOMCs were evaluated using electrochemical analyses such as CV,EIS and GCD in 1 M H2SO4 medium.Among the various prepared HOMCs,sample NPOMC showed a high specific capacitance of 355 Fg~(-1)at a current density of 0.5 Ag~(-1)due to the heteroatoms.Moreover,the symmetric device fabricated using NPOMC exhibited 98% columbic efficiency with 98% capacitance retention after 1000 cycles at 2 Ag~(-1)current density.
