Journal ArticleDOI
Glutathione-Protected Gold Clusters Revisited: Bridging the Gap between Gold(I)−Thiolate Complexes and Thiolate-Protected Gold Nanocrystals
TL;DR: It is proposed that a series of the isolated Au:SG clusters corresponds to kinetically trapped intermediates of the growing Au cores, and it is revealed that the subnanometer-sized Au clusters thiolated constitute a distinct class of binary system which lies between the Au(I)-thiolate complexes and thiolate-protected Au NCs.
Journal ArticleDOI
Size-specific catalytic activity of polymer-stabilized gold nanoclusters for aerobic alcohol oxidation in water.
TL;DR: A reaction mechanism for alcohol oxidation catalyzed by Au:PVP NCs is proposed in which a superoxo-like molecular oxygen species adsorbed on the surface of the small Au NCs abstracts a hydrogen atom from the alkoxide.
Journal ArticleDOI
Effect of electronic structures of Au clusters stabilized by poly(N-vinyl-2-pyrrolidone) on aerobic oxidation catalysis.
TL;DR: It is proposed that electron transfer from the anionic Au cores of Au:PVP into the LUMO (pi*) of O(2) generates superoxo- or peroxo -like species, which plays a key role in the oxidation of alcohol.
Journal ArticleDOI
Magic-numbered Aun clusters protected by glutathione monolayers (n = 18, 21, 25, 28, 32, 39): Isolation and spectroscopic characterization
TL;DR: In this article, small gold clusters protected by a glutathione (GSH) monolayer were fractionated into six components by polyacrylamide gel electrophoresis, and their chemical compositions were investigated by electrospray ionization mass spectroscopy.
Journal ArticleDOI
Nonscalable oxidation catalysis of gold clusters.
TL;DR: The non-scalable catalysis of Au clusters that are reported here points to the possibility that novel catalysis beyond that expected from bulk counterparts can be developed simply by reducing the catalyst size to the sub-2 nm regime.
