Heterogeneous rhodium-tin nanoparticles: highly active and durable electrocatalysts for the oxidation of ethanol

Abstract

Facile synthesis of Rh-Sn catalysts for the electrocatalytic oxidation of ethanol is carried out via a surfactant-free microwave-assisted method. The bifunctional mechanism and electronic modification with C-C bond splitting enable this electrocatalyst to be remarkably active and durable at high fuel concentrations, which allows for a significant reduction in the volume and weight of the fuel cell system.
