Onset of Catalytic Activity of Gold Clusters on Titania with the Appearance of Nonmetallic Properties
Mika Valden,X. Lai,D. W. Goodman +2 more
TL;DR: Results suggest that supported clusters, in general, may have unusual catalytic properties as one dimension of the cluster becomes smaller than three atomic spacings.

Ligand effects in homogeneous Au catalysis.
TL;DR: The ways in which selectivity can be controlled in homogeneous Au catalysis are enumerated, in the hope that lessons to guide catalyst selection and the design of new catalysts may be distilled from a thorough evaluation of ligand, counterion, and oxidation state effects as they influence chemo-, regio-, and stereoselectivity in homogeneity AuCatalysis.
