英文摘要	preferential co oxidation (prox) under hydrogen-rich atmosphere was investigated over ce-promoted pt/gamma-al2o3 catalysts. the preparation procedures and conditions, including co-deposition-precipitation (cp) sequential deposition-precipitation (sp), and deposition-precipitation temperature, had great impacts on the catalytic activity. among the catalysts investigated, the pt-ce/gamma-al2o3-cp-80 catalyst prepared by co-deposition-precipitation at 80 degrees c showed the best catalytic performance with the maximum co conversion of 85% at 120 degrees c. the catalysts prepared under different conditions were further characterized by temperature-programmed reduction (h-2-tpr) and in situ drifts, and the promoting role of ce was clarified.
