چکیده انگلیسی
N-doped mesoporous carbon was prepared by a one-step method of pyrolyzing the mixture of milk powder and potassium hydroxide without templates. The N-doped mesoporous carbon (NMPC) with microporous and mesoporous had a specific surface area of 2145.5Â m2Â gâ1 and a pore volume of 1.25Â cm3Â gâ1. X-ray photoelectron spectroscopy analysis showed that the nitrogen content of NMPC was 2.5 at%. The NMPC exhibited a high specific capacitance (396.5Â FÂ gâ1Â at 0.2Â AÂ gâ1) and excellent stability (capacitance retention of 95.9% after 2000 cycles at 50Â mVÂ sâ1) as a supercapacitor electrode material. Moreover, the NMPC as a fuel cell cathode catalyst also showed effective activity for oxygen reduction reaction in alkaline solution. The results demonstrate that the NMPC is a promising electrode material for supercapacitors and fuel cells.
