Title

The Anodic Oxidation of Ethylene on Heterogeneous AuPt Alloys

Abstract

The anodic oxidation of ethylene on AuPt alloys has been studied at 80°C in aqueous solutions (pH 0·35-12·7). The over-all compositions of the alloys were 80, 60, 40 and 20 at-% Au. Analyses showed them to possess two-phase, α 1 (Pt-rich) and α 2 (Au-rich), microstructures. The effects of potential, temperature, electrolyte pH and ethylene partial pressure on cd were determined and the results interpreted in terms of separate reactions occurring on the individual phases. The reactions on the Au-rich and Pt-rich phases were similar to those on pure Au and Pt, respectively. Mathematical equations describing the reactions are presented to correlate the experimental data. © 1971.
