Journal ArticleDOI
Interaction of NH3 with Cu-SSZ-13 Catalyst: A Complementary FTIR, XANES, and XES Study.
Filippo Giordanino,Elisa Borfecchia,Kirill A. Lomachenko,Andrea Lazzarini,Giovanni Agostini,Erik Gallo,Alexander V. Soldatov,Pablo Beato,Silvia Bordiga,Carlo Lamberti +9 more
TL;DR: Spectroscopic techniques are employed to get an insight into the geometry and electronic structure of Cu centers upon NH3 adsorption, revealing for the first time in Cu-SSZ-13 the presence of linear Cu(+) species in Ofw-Cu-NH3 or H3N- Cu- NH3 configuration.
Journal ArticleDOI
Taking snapshots of photosynthetic water oxidation using femtosecond X-ray diffraction and spectroscopy
Jan Kern,Rosalie Tran,Roberto Alonso-Mori,Sergey Koroidov,Nathaniel Echols,Johan Hattne,Mohamed Ibrahim,Sheraz Gul,Hartawan Laksmono,Raymond G. Sierra,Richard J.

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
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
Low-dimensional systems investigated by x-ray absorption spectroscopy: a selection of 2D, 1D and 0D cases
Lorenzo Mino,Giovanni Agostini,Elisa Borfecchia,Diego Gianolio,Andrea Piovano,Erik Gallo,Erik Gallo,Carlo Lamberti +7 more
TL;DR: X-ray absorption spectroscopy (XAS) is a powerful tool for the characterization of such kinds of systems, owing to its chemical selectivity and high sensitivity in interatomic distance determination as discussed by the authors.
Journal ArticleDOI
Selective catalytic reduction of NO over Fe-ZSM-5: mechanistic insights by operando HERFD-XANES and valence-to-core X-ray emission spectroscopy.
Alexey Boubnov,Hudson Wallace Pereira de Carvalho,Dmitry E. Doronkin,T. Günter,Erik Gallo,Andrew J. Atkins,Christoph R. Jacob,Jan-Dierk Grunwaldt +7 more
TL;DR: The unique combination of techniques applied under realistic reaction conditions and the corresponding catalytic data unraveled the adsorption of ammonia via oxygen on the iron site and supports a mechanism where adsorbed NOx reacts with ammonia coordinated to the Fe(3+) site yielding Fe(2+) whose reoxidation is slow.
