Hydride-induced ligand dynamic and structural transformation of gold nanoclusters during a catalytic reaction

Hydride-induced ligand dynamic and structural transformation of gold nanoclusters during a catalytic reaction

Quasi-homogeneous ligand-protected gold nanoclusters (Au NCs) with atomic precision and welldefined structure offer great opportunity for exploring the catalytic nature of nanogold catalysts at a molecular level. Herein, using real-time electrospray ionization mass spectrometry (ESI-MS), we have suc...

Hydride-induced ligand dynamic and structural transformation of gold nanoclusters during a catalytic reaction
description Quasi-homogeneous ligand-protected gold nanoclusters (Au NCs) with atomic precision and welldefined structure offer great opportunity for exploring the catalytic nature of nanogold catalysts at a molecular level. Herein, using real-time electrospray ionization mass spectrometry (ESI-MS), we have successfully identified the desorption and re-adsorption of p-mercaptobenzoic acid (p-MBA) ligands from Au25(p-MBA)18 NC catalysts during the hydrogenation of 4-nitrophenol in solution.

The adsorption of hydrides (from NaBH4) is identified as the determining factor that could induce the ligand dynamic and structural transformation of NC catalysts. This study provides fundamental insights into the catalytic nature of Au NCs, including catalytic mechanism, active species and stability of Au NC catalysts during a catalytic reaction.
