THE CHEMISORPTION OF HYDROGEN SULFIDE, METHYL SULFIDE, AND CYCLOHEXENE ON SUPPORTED NICKEL CATALYSTS
Magnetization measurements on supported nickel catalysts showed that hydrogen sulfide is dissociatively chemisorbed, forming four chemisorptive bonds with the nickel surface. This is confirmed by deuterium exchange results. The mechanism of chemisorption of methyl sulfide is strongly temperature dependent. It is associatively adsorbed at room temperature forming two chemisorptive bonds, but at higher temperatures extensive C---H and C---S bond rupture occurs. Cyclohexene is dissociatively chemisorbed at 25 deg C, forming two adsorbed hydrogen atoms and a diadsorbed C/sub 6/H/sub 8/ radical. This conclusion is confirmed by deuterium exchange experiments.
