Abstract

XPS and cyclic voltammetry were used to characterize 4.9 wt.% platinum-on-graphite catalysts used for the oxidn. with O2 of Me a-D-glucoside in aq. soln. Cyclic voltammetry indicates that a surface oxidic layer is formed on the Pt particles upon exposure to air. This oxidn. could not be confirmed by XPS. The oxidn. of Me a-D-glucoside in the liq. phase is accompanied by growth of the Pt particles. Open-circuit potential measurements indicated an increasing O coverage of the Pt surface during reaction.
