Sulfation of the 1%Pt-1%Sn/β₯-Al 2 O 3 catalyst, resulted in an enhancement of the conversion of NO and C 3 H 8 during the C 3 H 8 -NO-O 2 reaction. IR study showed the formation of bulk aluminum sulfate and surface tin sulfate. The presence of tin sulfate in the catalyst enhances C 3 H 8 oxidation b
