英文摘要 | employing hot tungsten filament to thermal dissociate molecular hydrogen, we generated gas phase atomic hydrogen under ultra-high vacuum (uhv) conditions and investigated its interaction with pt(111) surface. thermal desorption spectroscopy (tds) results demonstrate that adsorption of molecular hydrogen on pt(111) forms surface h-ad species whereas adsorption of atomic hydrogen forms not only surface h-ad species but also bulk h-ad species. bulk h-ad species is more thermal-unstable than surface h-ad species on pt(111), suggesting that bulk h-ad species is more energetic. this kind of weakly-adsorbed bulk h-ad species might be the active hydrogen species in the pt-catalyzed hydrogenation reactions. |
