Journal ArticleDOI
Aqueous Au-Pd colloids catalyze selective CH4 oxidation to CH3OH with O2 under mild conditions
Nishtha Agarwal,Simon J. Freakley,Rebecca McVicker,Sultan Althahban,Nikolaos Dimitratos,Qian He,David J. Morgan,Robert Leyshon Jenkins,David J. Willock,Stuart Hamilton Taylor,Christopher J. Kiely,Christopher J. Kiely,Graham J. Hutchings +12 more
TL;DR: It is demonstrated that the resulting methanol incorporated a substantial fraction of gas-phase O2, suggesting that the controlled breakdown of H2O2 activates methane, which subsequently incorporates molecular oxygen through a radical process.
Journal ArticleDOI
Tuning of catalytic sites in Pt/TiO2 catalysts for the chemoselective hydrogenation of 3-nitrostyrene
Margherita Macino,Alexandra J. Barnes,Sultan Althahban,Sultan Althahban,Ruiyang Qu,Emma K. Gibson,David J. Morgan,Simon J. Freakley,Nikolaos Dimitratos,Nikolaos Dimitratos,Christopher J. Kiely,Christopher J. Kiely,Xiang Gao,Andrew M. Beale,Andrew M. Beale,Donald Bethell,Qian He,Meenakshisundaram Sankar,Graham J. Hutchings +18 more
TL;DR: In this article, a 0.2 wt% Pt/TiO2 catalyst for the chemoselective hydrogenation of 3-nitrostyrene is presented, where the post-synthetic heat treatment procedure is combined with control over the metal loading.
Journal ArticleDOI
Elucidating the role of CO2 in the soft oxidative dehydrogenation of propane over ceria-based catalysts
Ewa Nowicka,Ewa Nowicka,Christian Reece,Sultan Althahban,Khaled M. H. Mohammed,Khaled M. H. Mohammed,Simon A. Kondrat,Simon A. Kondrat,David J. Morgan,Qian He,David J. Willock,Stanislaw E. Golunski,Christopher J. Kiely,Christopher J. Kiely,Graham J. Hutchings +14 more
TL;DR: A mixed oxide support containing Ce, Zr, and Al was synthesized using a physical grinding method and applied in the oxidative dehydrogenation of propane using CO2 as the oxidant as discussed by the authors.
Journal ArticleDOI
Synergy and Anti-Synergy between Palladium and Gold in Nanoparticles Dispersed on a Reducible Support.
James H. Carter,Sultan Althahban,Ewa Nowicka,Simon J. Freakley,David J. Morgan,Parag Shah,Stanislaw E. Golunski,Christopher J. Kiely,Graham J. Hutchings +8 more
TL;DR: It is proposed that peripheral Au0* species form part of the active centers in the most active catalysts for the three gas-phase reactions, in contrast, the active sites for the selective oxidation of benzyl alcohol are generally thought to be electronically modified gold atoms at the surface of the nanoparticles.
Journal ArticleDOI
Au–Pd separation enhances bimetallic catalysis of alcohol oxidation
Xiaoyang Huang,Ouardia Akdim,Mark Douthwaite,Kai Wang,Xiang Zhao,Richard J. Lewis,Samuel Pattisson,Isaac T Daniel,Peter J. Miedziak,Greg Shaw,David J. Morgan,Sultan Althahban,Thomas E. Davies,Qian He,Fei Wang,Jile Fu,Donald Bethell,Steven McIntosh,Christopher J. Kiely,Graham J. Hutchings +19 more
TL;DR: In this paper , the authors show that separating the gold and palladium components in bimetallic carbon-supported catalysts can almost double the reaction rate compared with that achieved with the corresponding alloy catalyst.
