A novel iron nitride-activated carbon composite was synthesized via hydrothermal and ammonia treatments. The impregnation of mesoporous carbon with an iron precursor under hydrothermal conditions resulted in an outstanding specific capacitance of 507 F g −1 at 0.5 A g −1 and a remarkable rate capability of 72% for the hybrid-based supercapacitor electrode. Hydrothermal-assisted impregnation followed by NH 3 annealing resulted in the fabrication of a novel iron nitride-carbon hybrid as an electrode material with a remarkable specific capacitance of 525 F g −1 for high-performance supercapacitors.
