Three types of platinum catalysts, Pt/SiO,, Pt/y-Al,O, and Pt/ZrO, were examined for the oxidation of NO to NO, and of SO, to SO,. The activity order for both oxidation reactions was found to be: Pt/SiO, > Pt/y-Al,O, > Pt/ZrO,. The effect of Pt loading and Pt dispersion on the catalytic activity and selectivity was examined. Over Pt/SiO,, the specific activities were found to be strongly size-dependent, the larger Pt particles exhibiting higher specific activity than the smaller ones. Over the… CONTINUE READING
