Identification of Highly Active Fe Sites in (Ni,Fe)OOH for Electrocatalytic Water Splitting
Daniel Friebel,Mary W. Louie,Mary W. Louie,Michal Bajdich,Kai E. Sanwald,Kai E. Sanwald,Yun Cai,Yun Cai,Anna M. Wise,Mu Jeng Cheng,Mu Jeng Cheng,Dimosthenis Sokaras,Tsu-Chien Weng,Roberto Alonso-Mori,Ryan C. Davis,John R. Bargar,Jens K. Nørskov,Anders Nilsson,Anders Nilsson,Alexis T. Bell,Alexis T.

TL;DR: It is established that Fe(3+) in Ni(1-x)Fe(x)OOH occupies octahedral sites with unusually short Fe-O bond distances, induced by edge-sharing with surrounding [NiO6] octahedra, which results in near optimal adsorption energies of OER intermediates and low overpotentials at Fe sites.
Journal ArticleDOI

TL;DR: The spectra show that the initial O-O bond formation, coupled to Mn-reduction, does not yet occur within 250 μs after the third flash, and the initial frames in a molecular movie of the structural changes during the catalytic reaction in photosystem II are represented.
Journal ArticleDOI

TL;DR: It is demonstrated that the ”probe before destroy” approach using an X-ray free electron laser works even for the highly-sensitive Mn4CaO5 cluster in PS II at room temperature, and that these data are comparable to those obtained in synchrotron radiation studies.
Journal ArticleDOI
Reflections on hard X-ray photon-in/photon-out spectroscopy for electronic structure studies
Pieter Glatzel,Tsu-Chien Weng,Kristina O. Kvashnina,Janine C. Swarbrick,Marcin Sikora,Erik Gallo,Erik Gallo,Nikolay Smolentsev,Nikolay Smolentsev,Roberto Alonso Mori +9 more
TL;DR: In this article, a collection of considerations on non-resonant and resonant XES with the aim to guide the experimentalist to make good use of this technique is presented.
Journal ArticleDOI
Manganese Kβ X-ray emission spectroscopy as a probe of metal-ligand interactions.

TL;DR: The Mn XES findings serve as an important calibration for future applications to manganese active sites in biological and chemical catalysis and assess the contributions to the energies and intensities.
