Remarkable enhancement in ligand-exchange reactivity of thiolate-protected Au25 nanoclusters by single Pd atom doping

The effect of Pd doping on the ligand-exchange reactivity of Au-25(SC12H25)(18) was studied by comparing the ligand-exchange reactivity of [Au-25(SC12H25)(18)](-) and [PdAu24(SC12H25)(18)](0) and the results clearly demonstrate that, regardless of the kind of incoming thiols and solvents, Pd doping greatly increases the rate of ligand exchange of Au-25(SC12H25)(18), indicating an enhanced ease of ligand exchange.
