Abstract |
Silica supported copper-manganese oxide catalyst was prepared by a redox-precipitation and alkali silicate titration method. In a typical process, nano-sized CuO:MnO2 mixed oxide particle was first prepared by a titration of manganese and copper acetate aqueous solution into potassium permanganate solution. Then alkali silicate solution (Na2SiO3 solution) was titrate into the reaction solution to adjust the pH in the range of 4.5 ~ 7.0. The porous parameters such as specific surface area, pore volume and pore size were calculated from nitrogen adsorption-desorption isotherm analysis as a function of solution pH. The gas removal activity of the porous catalysts was also compared using CO, NH3, CH3CHO.
