Rejuvenating sunlight : Supported Au–Cu bimetallic alloy nanoparticles promote aerobic oxidation at room temperature under visible light ( λ >450 nm) irradiation with little deactivation by the oxidation of surface Cu atoms by oxygen. This is achieved through the reduction of oxidized surface Cu atoms by the surface Au atoms, a process which is activated by visible‐light irradiation, even by sunlight.
