Abstract

In recent years, atomically precise gold nanoclusters [Aun(SR)m, where SR=thiolate] have emerged as a new promising class of catalysts for a wide range of reactions, including selective oxidation, chemoselective hydrogenation and carbon–carbon coupling reactions. These well-defined gold nanoclusters possess a sizable bandgap and quantized electronic structure, as opposed to the continuous conduction band in metallic gold nanoparticles. Moreover, some of the Aun(SR)m nanoclusters have been characterized crystallographically. These Aun(SR)m nanocluster model catalysts provide a unique opportunity to correlate the catalytic performance of nanogold catalysts with the atomic structure of gold nanoclusters and eventually to understand the mechanism of the gold nanocluster-catalysed processes at the atomic level.
