That sulfur is responsible for suppressing hydrocracking of organic molecules on Pt is consistent with the work of Fischer and Kelemen (88) showing that bonding of benzene on Pt(100) is sufficiently modified by preadsorbed sulfur to enable an increasing fraction of the adsorbed benzene to desorb at elevated temperatures rather than to dehydrogenate.
