摘要

The effect of metal loading on structural properties and CO oxidation activity of Coprecipitated Co/Al_2O_3 catalysts was investigated.The results indicated the participation of cobalt in the Co-Al skeleton for all Coprecipitated samples.Environmental-SEM-EDXS studies showed that at loadings higher than ca.15 wt.-%,cobalt formed layer-by-layer clusters on the surface;16.8 wt.-% Co/Al_2O_3 displayed the highest activity and stability in CO oxidation.
