제목 Synthesis of highly ordered mesoporous CeO2 and 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. The structure of the catalysts and the WGS reaction intermediate were characterized using powder X-ray diffraction (XRD), nitrogen sorption & adsorption isotherms, scanning electron microscopy (SEM), temperature programmed surface experiments. A 20 wt% CuxCo3-xO4/meso-CeO2 catalyst displayed the highest catalytic activity among all the prepared catalysts. Beside high activity, the 20 wt% CuxCo3-xO4/meso-CeO2 catalyst also exhibited the stability under WGS conditions compared to 20 wt% CuxCo3-xO4.
