TL;DR: It is reported the first detailed observation of sulfur ligand migration from Au to the oxide support upon deposition and oxidative pre‐treatment, employing mainly S K‐edge XANES, which not only produces clean Au cluster surfaces but also the surrounding oxide support is modified by sulfur‐containing species.

TL;DR: In this article, the stability of Au25 and Au144 clusters, supported either on TiO2 or SiO2, was examined upon thermal air pretreatment and, for the first time, upon liquid phase oxidation reaction.

TL;DR: Atomically precise thiolate protected Au nanoclusters Au38(SC2H4Ph)24 on CeO2 were used for in-situ extended X-ray absorption fine structure/diffuse reflectance infrared fourier transform spectroscopy and ex situ scanning transmission electron microscopy–high-angle annular dark-field imaging/X-ray photoelectron spectroscope studies monitoring cluster structure changes induced by activation (ligand removal) and CO oxidation.

TL;DR: The combined analysis of in situ XAFS, operando DRIFTS, and ex situ XPS revealed the structural evolution of bimetallic PdAu nanoclusters, yielding a Pd single-site catalyst of 2.7 nm average particle size with improved CO oxidation activity.

TL;DR: The first successful ligand exchange on supported (immobilized) Au11 nanoclusters is reported, and different structures/compounds were formed depending on the nature of the incoming ligand, which may allow controlled nanocluster functionalization.
