Influence of Transition Metals in Ordered Mesoporous Co3O4 based Composites on The Preferential Oxidation of CO |
| 초록 |
Noble metals were recognized as the promising candidates for effective CO-PROX reaction, however noble metal catalysts were not attractive due to their high costs. Recently, transition metal oxides have been investigated in order to escape from noble metal catalysis system. Among the candidates, Co3O4 is a well-known CO-PROX catalyst which exhibits high catalytic performance (CO oxidation by O2) at low temperature, and ordered mesoporous Co3O4 showed excellent performance due to its high surface area. In this work, we enhanced the CO-PROX performance of ordered mesoporous Co3O4 using 2 strategies: Co metal incorporation with ordered mesoporous Co3O4 framework and other transition metal doping. Thus, we prepared ordered mesoporous Co3O4, Co/Co3O4, and transition metals (Cu, Fe, etc.) and Co3O4 nano-composites for CO-PROX by nano-casting method using KIT-6 silica hard template. The CO-PROX activity was improved when Co metal was incorporated with Co3O4 framework. |
