Abstract

An effective strategy involving the corrosion of partial-surface-passivated Cu nanoparticles is proposed for synthesizing transition-metal-based Cu–Au alloy nanocages. Time-dependent X-ray absorption spectroscopy demonstrates that the hollow-cage Cu–Au alloy nanostructure is formed by sequential erosion of the partial surface and interior Cu and by the alloying of Au and Cu.
