Anisotropy diffusion in monolayer growth of Au on Cu (110) by kinetic Monte Carlo method

Silver Clusters with Adatoms as a Catalyst for the Oxygen Reduction Reaction

“…We propose that, different from atomic arrays in a continuous surface, the isolated atom distributing on the surface of a catalyst presents low coordination numbers and changes the local electronic environment, thus enhancing adsorptive and catalytic capability. In reality, the adatoms on metal surfaces are thermodynamically unstable, and they may disappear by aggregating into clusters or combining with defective sites . Particularly, metal nanoparticles and clusters own many unsaturated sites, making it more difficult to stabilize the adatoms on their surface .…”

“…In reality, the adatoms on metal surfaces are thermodynamically unstable, and they may disappear by aggregating into clusters or combining with defective sites. 27 Particularly, metal nanoparticles and clusters own many unsaturated sites, making it more difficult to stabilize the adatoms on their surface. 28 Electrolysis was proven to be effective in the synthesis of metallic clusters, 29 where the metal anode is first oxidized into cations, and then the cations migrate to the cathode and are reduced into metallic monomers.…”
