- Abstract
- The reduction of NOx by CO was studied over gold catalyst supported on ceria and ceria-alumina. The mixed supports with different CeO2/
Al2O3 ratios were prepared by co-precipitation. The catalysts were characterized by means of XRD, TPR, XPS and Raman spectroscopy. The
addition of alumina led to a slight enlargement of the gold particles, while the ceria particle size was decreased. Deeper oxygen vacancies formation
in the presence of alumina was detected by TPR, XPS and Raman spectroscopy, compared to the pure ceria support. The samples exhibited a high
and stable activity and 100% selectivity towards N2 was reached at 200 8C.
