Water adsorption on clean and oxygen covered Pd(100) has been studied by electron energy loss spectroscopy and low energy electron diffraction. On the clean surface water is associatively adsorbed and reveals hydrogen bonding. Hydroxyl is produced upon water adsorption on oxygen precovered Pd(100). The hydroxyl molecule is adsorbed with its molecular axis significantly tilted away from the surface normal. A study of the reactivity of coadsorbed hydrogen and hydroxyl yields new information on the catalytic oxidation of hydrogen on Pd(100). The following reaction path could be inferred: Oad+Had→OHad, 2OHad→Oad+H2Oad→Oad+H2Og.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
