Synthesis of Sinter-Resistant Au@Silica Catalysts Derived from Au25 Clusters
Gold clusters exhibit remarkable catalytic activity for many reactions such as carbon monoxide oxidation, alcohol, alkene, and hydrocarbon oxidations, and reduction reactions at low temperatures. However, several previous ...
Following the Thermal Activation of Au25(SR)18 Clusters for Catalysis by X-Ray Absorption Spectroscopy
(American Chemical Society, 2013)
We show the thermal activation of phenylethanethiolate (L = SC8H9) and hexanethiolate (L = SC6H13) Au25L18 monolayer protected clusters (MPCs) on carbon black supports, followed by characterization with extended X-ray ...
Following the Reactivity of Au25(SC8H9)18 - Clusters With Pd2+ and Ag+ Ions Using in Situ X-ray Absorption Spectroscopy: A Tale of Two Metals
(American Chemical Society, 2015)
This work examines the reaction between Au25(SC8H9)18– clusters with palladium acetate (Pd2+) and silver nitrate (Ag+) using UV–vis, transmission electron microscopy (TEM), extended X-ray absorption spectroscopy (EXAFS), ...
Following the Thermal and Chemical Activation of Supported Au Clusters using X-ray Absorption Spectroscopy
(Royal Society of Chemistry, 2016)
Al2O3-supported Au25(SC8H9)18 clusters with various Au loadings were thermally and chemically treated in order to determine the most efficient method towards the removal of thiolate stabilizers while avoiding unwanted ...
