One-step nanocasting synthesis of nitrogen and phosphorus dual heteroatom doped ordered mesoporous carbons for supercapacitor application

Abstract

N and P dual heteroatom doped ordered mesoporous carbon was synthesized and exhibited enhanced specific capacitance (220 F g⁻¹ at 1 A g⁻¹), good rate capability (178 F g⁻¹ at 16 A g⁻¹ with 81% capacitance retention) and excellent cycling stability (91% after 3000 cycles).
