Abstract |
Silica supported Mn based oxide catalysts, CuO:MnO2, CuMn2O4, and Mn3O4, were prepared by a redox-precipitation and alkali silicate titration method. In a typical process, nano-sized oxide particle was first prepared by a redox precipitation, followed by a basic alkali silicate (Na2SiO3 solution) titration to obtain porous materials. Such prepared oxide catalysts were characterized by X-ray diffraction(XRD), X-ray fluorescence(XRF), temperature-programmed oxidation(TPO), NH3 temperature-programmed desorption(TPD) analyses. The porous parameters such as specific surface area, pore volume and pore size were calculated from nitrogen adsorption-desorption isotherm analysis. The gas removal efficiency of the porous catalysts was also compared using CO, NH3, CH3CHO, NO2, and H2S. |
