Journal ArticleDOI
Toward the rational design of non-precious transition metal oxides for oxygen electrocatalysis
Wesley T. Hong,Marcel Risch,Kelsey A. Stoerzinger,Alexis Grimaud,Jin Suntivich,Yang Shao-Horn +5 more
TL;DR: In this article, the state-of-the-art understanding of non-precious transition metal oxides that catalyze the oxygen reduction and evolution reactions is discussed, with an outlook on the opportunities in future research within this rapidly developing field.
Journal ArticleDOI
Activating lattice oxygen redox reactions in metal oxides to catalyse oxygen evolution
Alexis Grimaud,Oscar Diaz-Morales,Binghong Han,Wesley T. Hong,Yueh-Lin Lee,Livia Giordano,Livia Giordano,Kelsey A. Stoerzinger,Marc T. M. Koper,Yang Shao-Horn +9 more
TL;DR: Using in situ 18O isotope labelling mass spectrometry, direct experimental evidence is provided that the O2 generated during the OER on some highly active oxides can come from lattice oxygen.
Journal ArticleDOI
Double perovskites as a family of highly active catalysts for oxygen evolution in alkaline solution.
Alexis Grimaud,Kevin J. May,Christopher E. Carlton,Yueh-Lin Lee,Marcel Risch,Wesley T. Hong,Jigang Zhou,Yang Shao-Horn +7 more
TL;DR: The versatility of the perovskite structure is exploited to search for oxide catalysts that are both active and stable and can be explained by having the O p-band centre neither too close nor too far from the Fermi level, which is computed from ab initio studies.
Journal ArticleDOI
Anionic redox processes for electrochemical devices.
TL;DR: Understanding and controlling anionic redox processes is pivotal for the design of new Li-ion battery and water-splitting materials and will help improve the quality of existing and new lithium-ion batteries.
Journal ArticleDOI
Charge-transfer-energy-dependent oxygen evolution reaction mechanisms for perovskite oxides
Wesley T. Hong,Kelsey A. Stoerzinger,Yueh-Lin Lee,Livia Giordano,Livia Giordano,Alexis Grimaud,Alyssa M. Johnson,Jonathan Hwang,Ethan J. Crumlin,Wanli Yang,Yang Shao-Horn +10 more
TL;DR: In this paper, the authors use soft X-ray emission and absorption spectroscopy of perovskites to analyze the partial density of states on an absolute energy scale, from which energetic barriers for electron transfer and surface deprotonation were estimated and correlated with OER activity.
