英文摘要The adsorptive desulfurization of thiophene on rapidly quenched skeletal Ni (RQ Ni) was investigated by XPS. At 298 K, thiophene in direct contact with RQ Ni undergoes C-S bond scission, forming metallocycle-like species and atomic sulfur on metallic nickel. Further exposure to thiophene leads to physisorbed thiophene. At 373 K, most of the physisorbed thiophene desorbs, with a small portion undergoing sulfur abstraction on the newly exposed nickel surface. The existence of alumina and hydrogen may block the further cracking of the metallocycle-like species at higher temperatures, which has been considered to be the dominant reaction pathway-on Ni single crystals. At 473 K, the C-1s peak disappears, leaving nickel sulfide on the surface.
