| 제목 | Mesoporous cobalt-manganese oxide catalysts for preferential CO oxidation in H2-rich stream |
| 초록 | Hydrogen, the fuel of PEMFC, is produced via the reforming of hydrocarbons and water-gas shift reaction were contains 0.5vol % - 2.0 vol % CO, which can poison Pt anode. Therefore, the concentration of CO must be reduced to below100ppm. It is known that the preferential oxidation (PROX) of CO in H2-rich is the simplest and cost-effective routes for the removal of CO in H2. The catalysts reported for PROX include supported noble metal catalysts such as Pt , Rh , Ru and Au catalysts and transition metal oxide catalysts, such as Co3O4, MnO2 , CuO-CeO2, Co3O4- CeO2 has been recognized as one of the promising candidates. Among these the Co3O4 was known to exhibit good catalytic performance for the oxidation of CO by O2 at lower temperatures. Also manganese catalysts recognize as a promoter cobalt oxide and copper oxide catalysts. Adding MnOx can be improved catalysts dispersion and interaction between support and active metal. In this present work, we were synthesized mesoporous Co3-xMnxO4 catalysts by using nano-replication method from mesoporous silica template of KIT-6. The mesoporous Co3-xMnxO4 catalysts exhibited high catalytic activity compared with both Co3O4 and Mn2O3. |
