Abstract

Abstract Active self-supported Pd₁Sn_x catalysts are synthesized by the sacrificial support method. Their catalytic activities towards C₁ to C₃ alcohol oxidation are determined in alkaline medium. The comparison of the activities allows discarding a first base-catalyzed deprotonation reaction of alcohol as oxidation rate-determining step, speaking up for mechanisms involving a C-adsorption of carbon bearing an alcohol function. It is also shown that desorption of dihydroxyacetone is the glycerol oxidation-limiting step at low potentials.
