Evidence for the involvement of weak chemisorption in CO oxidation on SnOx-supported Pt

Abstract

At 2168 cm–1 FTIR spectroscopy reveals one notable difference in the states of CO adsorbed on silica- and SnOx-supported Pt during chemisorption and catalysis; such a band is seen for Pt/SnOx but not for Pt/SiO2, this may correspond to weakly chemisorbed CO and because it exists only on the surface (Pt/SnOx) of high activity in CO oxidation, the presence of such species may be consistent with higher rates of this surface reaction on Pt/SnOx.
