Abstract:Pt–Cu catalysts supported on Al2O3 and Nb2O5 were studied for use in selective CO oxidation. The addition of copper enhanced the activity and selectivity of Pt–Cu/Nb2O5 at lower temperatures when compared to Pt/Nb2O5. On the other hand, copper addition was not beneficial in the case of Al2O3 supported catalysts.
Keywords:Selective CO oxidation   Pt&ndash  Cu   Pt/Al2O3   Pt/Nb2O5
