Ordered mesoporous NiCo 2 O 4 nanowires electrodes were prepared using SBA-15 as template through a hydrothermal impregnation method. X-ray diffraction, nitrogen adsorption-desorption and transmission electron microscopy were used to characterize the structure and morphology of the SBA-15 and NiCo 2 O 4 . The pseudocapacitive performance of the samples were tested by electrochemical workstation. The results demonstrate that the ordered mesoporous NiCo 2 O 4 electrode material exhibit excellent

... seudocapacitance. The specific capacitances were calculated to be 1079.6 F g -1 , 1012 F g -1 , 943.9 F g -1 and 820 F g -1 at current densities of 1 A g -1 , 2 A g -1 , 4 A g -1 and 10 A g -1 , respectively. The cycling stability during the 1000 cycles was more than 96%. Therefore, the ordered mesoporous NiCo 2 O 4 electrodes materials are an excellent supercapacitor electrode materials.
