Journal ArticleDOI
Continuous selective oxidation of methane to methanol over Cu- and Fe-modified ZSM-5 catalysts in a flow reactor
Jun Xu,Jun Xu,Robert Armstrong,Greg Shaw,Nicholas Dummer,Simon J. Freakley,Stuart Hamilton Taylor,Graham J. Hutchings +7 more
TL;DR: In this paper, a co-impregnation of ZSM-5 with Fe and Cu by chemical vapour impregnation yielded catalysts that showed high selectivity to methanol (>92% selectivity, 0.5% conversion), as the only product in the liquid phase.
Journal ArticleDOI
Partial Oxidation of Ethane to Oxygenates Using Fe- and Cu-Containing ZSM-5
Michael M. Forde,Robert Armstrong,Ceri Hammond,Qian He,Robert Leyshon Jenkins,Simon A. Kondrat,Nikolaos Dimitratos,Jose Antonio Lopez-Sanchez,Stuart Hamilton Taylor,David J. Willock,Christopher J. Kiely,Graham J. Hutchings +11 more
TL;DR: It is demonstrated that ethene is also formed and can be subsequently oxidized, and the mechanism of ethane oxidation involves carbon-based radicals, which lead to the high conversions the authors observe.
Journal ArticleDOI
Low temperature selective oxidation of methane to methanol using titania supported gold palladium copper catalysts
Mohd Hasbi Ab. Rahim,Robert Armstrong,Ceri Hammond,Nikolaos Dimitratos,Simon J. Freakley,Michael M. Forde,David J. Morgan,G. Lalev,Robert Leyshon Jenkins,Jose Antonio Lopez-Sanchez,Stuart Hamilton Taylor,Graham J. Hutchings +11 more
TL;DR: In this article, the selective oxidation of methane to methanol has been studied using trimetallic AuPdCu/TiO2 catalysts prepared by incipient wetness impregnation.
Journal ArticleDOI
Hydrogenation of CO2 to dimethyl ether over Brønsted acidic PdZn catalysts
Hasliza Bahruji,Robert Armstrong,Jonathan Ruiz Esquius,Wilm Jones,Michael Bowker,Graham J. Hutchings +5 more
TL;DR: In this paper, it was shown that PdZn alloys are active for CO2 hydrogenation to oxygenates, and that enhanced CO2 conversion is achievable through the introduction of Bronsted acid sites which promote dehydration of methanol to dimethyl ether.
Journal ArticleDOI
Base-free oxidation of glucose to gluconic acid using supported gold catalysts
Yeuling Cao,Yeuling Cao,Xi Liu,Sarwat Iqbal,Peter J. Miedziak,Jennifer K. Edwards,Robert Armstrong,David J. Morgan,Junwei Wang,Graham J. Hutchings +9 more
TL;DR: In this paper, the effect of post-synthesis treatments of treatment with water, or heating in air on the activity of 1.1%Au/TiO2 catalysts was studied for base-free oxidation of glucose.
