Abstract
Highly active and stable platinum-copper (PtCu) electrocatalysts are provided. The PtCu catalysts can be in the form of discrete, spherical PtCu nanoparticles that include a particle interior comprising platinum and copper, and a surface layer comprising platinum surrounding the particle interior. The PtCu nanoparticles can exhibit enhanced oxygen reduction reaction (ORR) activity as compared to other Pt-based catalysts for ORR. The PtCu nanoparticles are also active as electrocatalysts for the oxidation of small molecule organic compounds, including alcohols such as methanol and ethanol.
