Tuning the accessibility and activity of Au25(SR)18 nanocluster catalysts through ligand engineering

In this work, the effects of thiolate ligands (-SR, e.g., chain length and functional moiety) on the accessibility and catalytic activity of thiolate-protected gold nanoclusters (e.g., Au25(SR)18) for 4-nitrophenol hydrogenation is reported. The data suggest that Au25(SR)18 bearing a shorter alkyl...
