Metal-support effects in Pt/L-zeolite catalysts

Abstract

A series of Pt/L-zeolites with different cations (varying acidity) were prepared and characterized by H2 and CO chemisorption and competitive toluene/benzene hydrogenation. The ratio of adsorption equilibrium constants for toluene/benzene was extracted from rates of hydrogenation. The variation of this ratio across a series of alkaline-earth exchanged Pt/L-zeolites indicates that there is a varying support interaction with Pt clusters in the zeolite and suggests that the clusters interact electronically with the support.
