Abstract:
We have studied the adsorption, thermal and photochemical reactions of NO adsorbed on clean Ni(100), epitaxially grown NiO, and Ni(100) precovered with chemisorbed oxygen. The electronic and geometric structure of the substrate surfaces and the adsorbed NO molecules were investigated by electron spectroscopic techniques, i.e. HREELS, NEXAFS and LEED, whereas the thermal and photochemical properties of the adsorbate layer were probed using TPD and laser induced desorption, respectively.
