Abstract

Pt supported on activated carbon and Pt supported on graphite were characterized before, during, and after oxidn. of Me a-D-glucoside in water. The reversible deactivation is attributed to a solwly increasing oxygen surface coverage rather than to the formation of Pt oxide. Chemisorption takes place beyond the steady-state degree of oxygen coverage expected from the intrinsic initial reaction kinetics and causes a reversible decrease of the reaction rate. The irreversible deactivation is caused by the dissoln. and subsequent redeposition of Pt. The effect of the irreversible decrease of the Pt surface area on the specific reaction rate is strongly attenuated by an antipathetic structure sensitivity
