ASSERT Award: Mapping Electrochemical Oxidation Pathways at Modified-Metal Catalysts

Abstract

A small volume electrolysis technique that allows the quantitative determination of soluble by-products of electrochemical reactions on low surface area electrodes was developed during the project period. Chromatographic and wet-chemical assays were used to analyze for reaction by-products following brief electrolysis periods (5-10 min) of small (50-100 microliters) sample volumes. The technique was applied to investigate effects of surface structure and composition on the oxidation pathways of small organic molecules at single crystal electrodes, bulk Pt-Ru alloys and supported fuel cell catalysts.
