제목 | Water-gas shift reaction over CuxCo3-xO4/ mesoporous CeO2 catalyst |
초록 | We report on the low water-gas shift (WGS, CO + H2O →H2 + CO2) activity of CuxCo3-xO4 supported on highly ordered mesoporous ceria oxide with high surface area and a large pore volume. The preparation method was via a nano-replication method using a KIT-6 template to get highly ordered mesoporous CeO2 support, then loading CuxCo3-xO4 on the meso-CeO2 by an incipient wetness impregnation. A 30 wt% CuxCo3-xO4/meso-CeO2 catalyst displayed the highest catalytic activity among all the prepared catalysts. Beside high activity, the 30 wt% CuxCo3-xO4/meso-CeO2 catalyst also exhibited the stability under WGS conditions compared to 30 wt% CuxCo3-xO4. The loading of CuxCo3-xO4 on the ceria oxide favored the formation of O vacancies that facilitated the dissociation of water, preventing the dissociation of CO and the formation of methane. Because of the special chemical properties the more methane was product with the more CuxCo3-xO4 loading. |
