Abstract

Manganese oxide/mesoporous carbon (MnO2/MCs) spherical composites were prepared by hydrothermal method. The resorcinol and potassium permanganate were used as carbon source and manganese source,respectively. The morphology and pore character of the carbon materials were investigated by scanning electron microscopy(SEM), X-ray diffraction(XRD), and nitrogen adsorption-desorption. The measurements show the sample with the corresponding spherical morphology and mesoporous structure. By controlling the concentration of potassium permanganate, various amount of manganese in carbon/manganese oxide can be obtained. The composite was employed as the support of Au catalyst for CO oxidation. Different amount of gold has been deposited on the as-synthesized carbon sphere/manganese oxide, and the activity and stability of Au catalyst after sintered at 300°C has been tested. The 8%Au/MnO2/MCs-46 catalyst had obvious deactivation on stream after 65h reaction time at the reaction temperature of 185°C. Meanwhile, the sample further used as the supercapacitor electrode materials for electrochemical performance test. The specific capacitance of the MnO2/MCs-30 electrode is as high as 275 Fg-1 at 0.5 Ag-1.
