Özet:

 

The effect of metal loading on structural properties and CO  oxidation activity of coprecipitated Co/Al2O3 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/Al2O3 displayed the highest activity and stability in CO  oxidation.
