Pd–Au bimetallic catalysts: understanding alloy effects from planar models and (supported) nanoparticles
Feng Gao,D. Wayne Goodman +1 more
TL;DR: Pd-Au bimetallic catalysts often display enhanced catalytic activities and selectivities compared with Pd-alone catalysts, often caused by two alloy effects, i.e., ensemble and ligand effects.

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.

Gold catalysts prepared by coprecipitation for low-temperature oxidation of hydrogen and of carbon monoxide
TL;DR: In this paper, gold catalysts were prepared by coprecipitation from an aqueous solution of HAuCl4 and the nitrates of various transition metals, including Auα-Fe2O3, AuCo3O4, and AuNiO.
Journal ArticleDOI
Novel Gold Catalysts for the Oxidation of Carbon Monoxide at a Temperature far Below 0 °C
TL;DR: In this article, a variety of gold catalysts are used to catalyze the oxidation of carbon monoxide at temperatures as low as −70 °C and are stable in a moistened gas atmosphere.

Solvent-Free Oxidation of Primary Alcohols to Aldehydes Using Au-Pd/TiO2 Catalysts
Dan I. Enache,Jennifer K. Edwards,Philip Landon,Benjamin Solsona-Espriu,Albert Frederick Carley,Andrew A. Herzing,Masashi Watanabe,Christopher J. Kiely,David W. Knight,Graham J. Hutchings +9 more
TL;DR: It is shown that Au/Pd-TiO2 catalysts give very high turnover frequencies (up to 270,000 turnovers per hour) for the oxidation of alcohols, including primary alkyl alcohols and the addition of Au to Pd nanocrystals improved the overall selectivity.

The Structure of Catalytically Active Gold on Titania
Mingshu Chen,D. W. Goodman +1 more
TL;DR: Kinetic measurements for the catalytic oxidation of carbon monoxide show that the gold bilayer structure is significantly more active than the monolayer, thus eliminating particle shape and direct support effects.
