Thermodynamic explanation of the universal correlation between oxygen evolution activity and corrosion of oxide catalysts.
Tobias Binninger,Rhiyaad Mohamed,Kay Waltar,Emiliana Fabbri,Pieter Levecque,Rüdiger Kötz,Thomas J. Schmidt +6 more
TL;DR: It is proved from basic thermodynamic considerations that any metal oxide must become unstable under oxygen evolution conditions irrespective of the pH value, because of the thermodynamic instability of the oxygen anion in the metal oxide lattice.
Electronic metal-support interaction enhanced oxygen reduction activity and stability of boron carbide supported platinum.
Colleen Jackson,Graham Smith,Graham Smith,David W. Inwood,Andrew S. Leach,Penny S. Whalley,Mauro Callisti,Tomas Polcar,Andrea E. Russell,Pieter Levecque,Denis Kramer +10 more
TL;DR: Platinum nanoparticles supported on graphite-rich boron carbide show a 50–100% increase in activity in acidic media and improved cycle stability compared to commercial carbon supported platinum nanoparticles, showing that purely electronic metal-support interactions can significantly improve oxygen reduction activity.
The Effect of Platinum Loading and Surface Morphology on Oxygen Reduction Activity
Susan M. Taylor,Emiliana Fabbri,Pieter Levecque,Thomas J. Schmidt,Thomas J. Schmidt,Olaf Conrad +5 more
TL;DR: In this paper, the catalytic activity of Pt catalysts towards the oxygen reduction reaction (ORR) was investigated on a catalyst system developed by thermally induced chemical deposition of Pt on carbon.
Oleylamine Aging of PtNi Nanoparticles Giving Enhanced Functionality for the Oxygen Reduction Reaction.
Gerard M. Leteba,Gerard M. Leteba,Yi-Chi Wang,Yi-Chi Wang,Thomas J. A. Slater,Rongsheng Cai,Conor Byrne,Christopher Race,David R. G. Mitchell,Pieter Levecque,Neil P. Young,Stuart M. Holmes,Alex S. Walton,Angus I. Kirkland,Sarah J. Haigh,Candace Lang +15 more
TL;DR: In this paper, a solution-phase strategy was proposed to synthesize alloyed PtNi nanoparticles which demonstrate outstanding functionality for the oxygen reduction reaction (ORR) by using one-pot coreduction colloidal synthesis.
