Evolution of Oxygen–Metal Electron Transfer and Metal Electronic States During Manganese Oxide Catalyzed Water Oxidation Revealed with In Situ Soft X‑Ray Spectroscopy
Marc F. Tesch,Marc F. Tesch,Shannon A. Bonke,Shannon A. Bonke,Shannon A. Bonke,Travis E. Jones,Maryam N. Shaker,Maryam N. Shaker,Jie Xiao,Katarzyna Skorupska,Katarzyna Skorupska,Rik Mom,Jens Melder,Philipp Kurz,Axel Knop-Gericke,Robert Schlögl,Robert Schlögl,Rosalie K. Hocking,Alexandr N. Simonov +18 more
TL;DR: In situ XAS experiments at the O K-edge provide complementary evidence for the formation of O2 from water andoretical analysis of these data indicates increased hybridization of the Mn-O orbitals and withdrawal of electron density from the O ligand shell.
Journal ArticleDOI
Facile Protocol for Alkaline Electrolyte Purification and Its Influence on a Ni–Co Oxide Catalyst for the Oxygen Evolution Reaction
Ioannis Spanos,Marc F. Tesch,Mingquan Yu,Harun Tüysüz,Jian Zhang,Xinliang Feng,Klaus Müllen,Robert Schlögl,Anna K. Mechler +8 more
TL;DR: In this paper, a simple and effective electrochemical method to remove Fe impurities from commercial KOH electrolyte was proposed, which utilized a MoS2 catalyst deposited on porous Ni foam as both anode and anode.
Journal ArticleDOI
Introducing Ionic-Current Detection for X-ray Absorption Spectroscopy in Liquid Cells.
Daniela Schön,Daniela Schön,Jie Xiao,Ronny Golnak,Marc F. Tesch,Bernd Winter,Juan-Jesús Velasco-Vélez,Emad F. Aziz,Emad F. Aziz,Emad F. Aziz +9 more
TL;DR: The ionic-current detection, termed as total ion yield (TIY) in this study, also produces an undistorted Fe L-edge XA spectrum, indicating its promising role as a novel detection method for XAS studies in liquid cells.
Journal ArticleDOI

Dongyoon Shin,Anna K. Mechler,Sabita Bhandari,Marc F. Tesch,Shannon A. Bonke,Frédéric Jaouen,Sonia Chabbra,Christoph Pratsch,Alexander Schnegg,Anna K. Mechler +9 more
TL;DR: In this paper, it was shown that the side product, H2O2, which is known to damage FeNC catalysts, is suppressed by the presence of Pt and the formation of reactive oxygen species is additionally inhibited.
Journal ArticleDOI
X-Ray Absorption Spectroscopy of TiO2 Nanoparticles in Water Using a Holey Membrane-Based Flow Cell
Tristan Petit,Jian Ren,Jian Ren,Sneha Choudhury,Sneha Choudhury,Ronny Golnak,Sreeju Sreekantan Nair Lalithambika,Sreeju Sreekantan Nair Lalithambika,Marc F. Tesch,Jie Xiao,Emad F. Aziz,Emad F. Aziz +11 more
TL;DR: In this article, a new method to probe nanomaterials in liquid using a holey membrane-based flow cell is introduced, where the X-ray transmission of the membrane is increased, especially in the water window, compared to solid membranes.
