This critical review aims to update the recent development in the selective oxidation of organic compounds by gold catalysis, highlighting the progress in the last three years. Following the impressive developments in the last decades, several protocols for catalytic oxidation are today available, which are based on the extraordinary properties of gold in terms of catalytic activity, selectivity, reusability and resistance to poisons. Beside many other applications, gold can be recommended for green processes dedicated to fine chemicals, pharmaceuticals and the food industry owing to its recognized bio-compatibility. The collected literature is focused on experiments concerning the oxidation of different chemical groups and could be of interest, in the wide area of organic chemistry, for improving previous processes or for exploring new catalytic pathways (174 references).read more

The critical role of water at the gold-titania interface in catalytic CO oxidation
TL;DR: It is shown through kinetics and infrared spectroscopy that the presence of water can lower the reaction activation barrier by enabling OOH groups to form from adsorbed oxygen (see the Perspective by Mullen and Mullins).

Size- and support-dependency in the catalysis of gold
TL;DR: In this article, the adsorption properties and reactivities of gold are summarized in terms of their size dependency from bulk to fine particles, clusters and atoms, and the catalytic performances of gold markedly depend on dispersion, supports, and preparation methods.

Active Nonmetallic Au and Pt Species on Ceria-Based Water-Gas Shift Catalysts
TL;DR: It is reported here that for the class of nanostructured gold– or platinum–cerium oxide catalysts, which are active for the water-gas shift reaction, metal nanoparticles do not participate in the reaction.

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.
