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
Role of the support in gold-containing nanoparticles as heterogeneous catalysts
Meenakshisundaram Sankar,Qian He,Qian He,Rebecca V. Engel,Mala A. Sainna,Andrew J. Logsdail,Alberto Roldan,David J. Willock,Nishtha Agarwal,Christopher J. Kiely,Christopher J. Kiely,Graham J. Hutchings +11 more
TL;DR: It is clear that the support functionality can play a crucial role in tuning the catalytic activity that is observed and that advanced theory and characterization add greatly to the understanding of these fascinating catalysts.
Journal ArticleDOI
Low temperature selective oxidation of methane using gold-palladium colloids
Rebecca McVicker,Nishtha Agarwal,Simon J. Freakley,Simon J. Freakley,Qian He,Sultan Althahban,Stuart Hamilton Taylor,Christopher J. Kiely,Christopher J. Kiely,Graham J. Hutchings +9 more
TL;DR: In this article, the effect of the reaction conditions and the catalyst parameters have been systematically investigated for selective oxidation of methane using hydrogen peroxide using unsupported gold-palladium nanoparticles prepared using colloidal methods.
Journal ArticleDOI
The Direct Synthesis of H2O2 and Selective Oxidation of Methane to Methanol Using HZSM-5 Supported AuPd Catalysts
Richard J. Lewis,Alejandro Bara-Estaun,Nishtha Agarwal,Simon J. Freakley,Simon J. Freakley,David J. Morgan,Graham J. Hutchings +6 more
TL;DR: In this article, gold palladium nanoparticles supported on a commercial aluminosilicate (HZSM-5) prepared using a wet co-impregnation method were used to produce hydrogen peroxide from molecular H2 and O2 via the direct synthesis reaction.
Journal ArticleDOI
Gold–palladium colloids as catalysts for hydrogen peroxide synthesis, degradation and methane oxidation: effect of the PVP stabiliser
Simon J. Freakley,Nishtha Agarwal,Rebecca McVicker,Sultan Althahban,Sultan Althahban,Richard J. Lewis,David J. Morgan,Nikolaos Dimitratos,Christopher J. Kiely,Christopher J. Kiely,Graham J. Hutchings +10 more
TL;DR: In this paper, the authors compare colloidal AuPd nanoparticles stabilised with polyvinylpyrrolidone (PVP) with the same nanoparticles supported on TiO2 for the direct synthesis of hydrogen peroxide and methane oxidation to methanol.
