Journal ArticleDOI
Electrochemical corrosion of a glassy carbon electrode
Youngmi Yi,Gisela Weinberg,Marina Prenzel,Mark T. Greiner,Saskia Heumann,Sylvia Becker,Robert Schlögl +6 more
TL;DR: In this paper, the authors investigated the chemical resistance of glassy carbon under electrochemical oxidative conditions, which occur under oxygen-involving reactions like oxygen reduction reaction (ORR) and oxygen evolution reaction (OER).
Journal ArticleDOI
The electronic structure of iridium and its oxides
Verena Pfeifer,Verena Pfeifer,Travis E. Jones,Juan J. Velasco Vélez,Juan J. Velasco Vélez,Cyriac Massué,Cyriac Massué,Rosa Arrigo,Detre Teschner,Frank Girgsdies,Michael Scherzer,Michael Scherzer,Mark T. Greiner,Jasmin Allan,Maike Hashagen,Gisela Weinberg,Simone Piccinin,Michael Hävecker,Michael Hävecker,Axel Knop-Gericke,Robert Schlögl,Robert Schlögl +21 more
TL;DR: In this paper, the electronic structure of iridium oxide was investigated using synchrotron-based X-ray photoemission and absorption spectroscopies with theoretical calculations.
Journal ArticleDOI
The electronic structure of iridium oxide electrodes active in water splitting.
Verena Pfeifer,Verena Pfeifer,Travis E. Jones,J. J. Velasco Vélez,J. J. Velasco Vélez,Cyriac Massué,Cyriac Massué,Mark T. Greiner,Rosa Arrigo,Detre Teschner,Frank Girgsdies,Michael Scherzer,Michael Scherzer,Jasmin Allan,Maike Hashagen,Gisela Weinberg,Simone Piccinin,Michael Hävecker,Michael Hävecker,Axel Knop-Gericke,Robert Schlögl,Robert Schlögl +21 more
TL;DR: This investigation reveals a pre-edge feature in the O K-edge of highly catalytically active X-ray amorphous iridium oxides that is identified as O 2p hole states forming in conjunction with Ir(III) and these electronic defects in the near-surface region of the anionic and cationic framework are likely critical for the enhanced activity of amorphously irium oxides relative to their crystalline counterparts.
Journal ArticleDOI
Toward monodispersed silver nanoparticles with unusual thermal stability.
Junming Sun,Ding Ma,He Zhang,Xiumei Liu,Xiuwen Han,Xinhe Bao,Gisela Weinberg,Norbert Pfänder,Dang Sheng Su +8 more
TL;DR: The confinement of mesopores played a key role in improving the thermal stabilities of silver nanoparticles (stable up to 773 K without any observable coarsening), which is essential to the further investigations on their chemical (e.g., catalytic) properties.
