The loading method of microwave irradiation, possesses advantages of simpleness, speediness and uniformity. Herein, we tried to synthesize ordered mesoporous carbon CMK-3 loading nickel nanoparticles by a microwave irradiation method, in which ethylene glycol was used as a reducer and Ni(OAc)₂ as a origin of nickel, then the samples were calcined at low temperature converting to nickel oxide in an air furnace. X-ray diffraction (XRD), transmission electron microscopy and nitrogen adsorption were used to characterize the structure and cyclic voltammetry was utilized to test the electrochemical performance of the samples. The results indicated that microwave irradiation and calcination at low temperature made the small-angle XRD apex of CMK-3 weakened, specific surface area declined and pore volume reduced. The specific capacitance increased from 229.3 to 295.9 F/g, which is higher than the value of ordered mesoporous carbon loading MnO₂, RuO₂•xH₂O in some literatures. Consequently, the microwave synthesis is an effective loading method, and has promising application of foreground.
