Water adsorption on Pt(110)(1 × 2)

Water adsorption on Pt(110)(1 × 2) has been studied at 100 K by thermal desorption spectroscopy, ultraviolet electron spectroscopy, photoemission of adsorbed xenon and electron stimulated desorption ion angular distribution. At this temperature water is molecularly adsorbed as small clusters with a peculiar orientation from the ridges. When oxygen is preadsorbed at 300 K, water is partially dissociated giving hydroxyl radicals which recombine at high temperature.
