Tracking the restructuring of oxidized silver–indium

Small Ag 25 In 75 bimetallic nanoparticles, produced by laser vaporization, are found (after air transfer) to contain an indium–oxide shell surrounding a silver-rich alloyed phase. For high P H 2 and T s , the direct reduction of the indium oxide shell, immediately followed by the melting or the diffusion onto the carbon substrate of the reduced indium atoms, is found to be the dominant mechanism.
