Abstract

The chemical reactions undergone by both O2 and H2O on (a) rare earth (Tb), (b) rare-earth transition metal alloy (FeTbCo), (c) transition metal (Fe and Ti), and (d) transition metals, modified with thin overlayers of another metal (Fe/Ti), have been studied by surface photoelectron spectroscopies, starting with the clean metals in UHV environment. Various degrees of reactivity are indicated, especially for adsorption and dissociation of H2O, depending upon whether the pure metals are studied, or mixtures of metals, which change the type and extent of dissociation of H2O (oxide vs. hydroxide formation).
