Journal ArticleDOI
Tunable gold catalysts for selective hydrocarbon oxidation under mild conditions
Mathew D Hughes,Yi-Jun Xu,Patrick Jenkins,Paul McMorn,Philip Landon,Dan I. Enache,Albert Frederick Carley,Gary Anthony Attard,Graham J. Hutchings,Frank King,E. Hugh Stitt,Peter Johnston,Ken Griffin,Christopher J. Kiely +13 more
TL;DR: It is shown that nanocrystalline gold catalysts can provide tunable active catalysts for the oxidation of alkenes using air, with exceptionally high selectivity to partial oxidation products and significant conversions.
Journal ArticleDOI
Selective oxidation of glycerol to glyceric acid using a gold catalyst in aqueous sodium hydroxide
TL;DR: Glycerol is oxidised to glyceric acid with 100% selectivity using either 1% au/charcoal or 1% Au/graphite catalyst under mild reaction conditions.
Journal ArticleDOI
Oxidation of glycerol using supported Pt, Pd and Au catalysts
Silvio Carrettin,Paul McMorn,Peter Johnston,Ken Griffin,Christopher J. Kiely,Graham J. Hutchings +5 more
TL;DR: In this paper, the role of the base is discussed and it is proposed that the base aids the initial dehydrogenation via H-abstraction of one of the primary OH groups of glycerol and, in the way, the rate limiting step in the oxidation process is overcome.
Journal ArticleDOI
Identification of single-site gold catalysis in acetylene hydrochlorination
Grazia Malta,Simon A. Kondrat,Simon J. Freakley,Catherine Davies,Li Lu,Simon R. Dawson,Adam Thetford,Adam Thetford,Emma K. Gibson,Emma K. Gibson,David J. Morgan,Wilm Jones,Peter P. Wells,Peter Johnston,C. Richard A. Catlow,C. Richard A. Catlow,C. Richard A. Catlow,Christopher J. Kiely,Graham J. Hutchings +18 more
TL;DR: An in situ x-ray absorption fine structure study of gold/carbon (Au/C) catalysts under acetylene hydrochlorination reaction conditions is performed and it is demonstrated that highly active catalysts comprise single-site cationic Au entities whose activity correlates with the ratio of Au(I):Au(III) present.
Journal ArticleDOI
Discovery, Development, and Commercialization of Gold Catalysts for Acetylene Hydrochlorination
TL;DR: The use and disadvantages of the mercury catalyst and the advent of the gold catalysts for vinyl chloride monomer is discussed, and the nature of the active site and the possible reaction mechanism are discussed.
