Preparation of Porous Copper-Manganese Oxide Catalyst Utilizing Alkaline Silicate Solution |
| 초록 |
Nanoporous copper-manganese oxide catalyst was prepared by a redox-precipitation method utilizing basic alkali silicate solution (Na2SiO3) as a pH controlling agent and porous inorganic support. Upon titrating the sodium silicate solution during the redox precipitation reaction, the Cu:Mn mole ratio in the precipitate becomes close to the nominal composition of 1:4 along with the decrease of Cu2+ concentration in the residual solution, indicating that the addition of alkaline silicate solution is helpful to obtain stoichiometric oxide catalyst and the reduction of waste water. In addition. alkali silicate titration resulted in the increase of specific surface area of the catalyst powder mainly due to the micropore development. Concerning to the CO removal performance of the catalyst powder, the CO removal efficiency is increased as the sodium silicate content increased when the removal efficiency is normalized to the active CuO:MnO catalyst content. |
