摘要：
The oxidation of AuCu nanoparticles was studied as a function of composition and temperature. Oxidation rates at 110 degrees C were higher for NPs with higher Cu content, showing that Au stabilized the Cu. Electrochemistry measurements show that AuCu could be a promising catalyst for lowering the over potential of CO2 reduction.
