Journal ArticleDOI
Biofunctionalized conductive polymers enable efficient CO2 electroreduction.
Halime Coskun,Abdalaziz Aljabour,Abdalaziz Aljabour,Phil De Luna,Dominik Farka,T. Greunz,David Stifter,Mahmut Kus,Xueli Zheng,Min Liu,Achim Walter Hassel,Wolfgang Schöfberger,Edward H. Sargent,Niyazi Serdar Sariciftci,Philipp Stadler +14 more
TL;DR: An all-organic, that is, metal-free, electrocatalyst that achieves impressive performance comparable to that of best-in-class Ag electrocatalysts is reported, confirming the value of exploiting hydrogen-bonded sequences as effective catalytic centers for renewable and cost-efficient industrial CO2RR applications.
Journal ArticleDOI
XPS study of the effects of long-term Ar+ ion and Ar cluster sputtering on the chemical degradation of hydrozincite and iron oxide
R. Steinberger,Juliane Walter,T. Greunz,Jiri Duchoslav,M. Arndt,Serguei L. Molodtsov,Serguei L. Molodtsov,Dirk C. Meyer,David Stifter +8 more
TL;DR: In this article, the influence of different sputter parameters on the degradation kinetics of a single ion may cause severe damage to some materials, such as hydrozincite and FeO.
Journal ArticleDOI
Anderson‐Localization and the Mott–Ioffe–Regel Limit in Glassy‐Metallic PEDOT
Dominik Farka,Halime Coskun,Jacek Gasiorowski,Christoph Cobet,Kurt Hingerl,Lisa Maria Uiberlacker,Sabine Hild,T. Greunz,David Stifter,Niyazi Serdar Sariciftci,Reghu Menon,Wolfgang Schoefberger,Cezarina Cela Mardare,Achim Walter Hassel,Clemens Schwarzinger,Markus C. Scharber,Philipp Stadler +16 more
TL;DR: In this article, a conductive polymer synthesis strategy was proposed to achieve polymerization and doping simultaneously, thereby using an alternative nonmetal oxidant and thereby avoiding the introduction of excess energy that normally arises from exergonic polymerization.
Journal ArticleDOI
Investigation of the chemical stability of different Cr(VI) based compounds during regular X-ray photoelectron spectroscopy measurements
TL;DR: In this article, the influence of standard XPS measurements, using a modern system with monochromatic X-rays and a dual flood gun, on the chemical stability of several Cr(VI) compounds was investigated in depth.
Journal ArticleDOI
Metal-Free Hydrogen-Bonded Polymers Mimic Noble Metal Electrocatalysts.
Halime Coskun,Abdalaziz Aljabour,Phil De Luna,He Sun,Nobuyuki Nishiumi,Tsukasa Yoshida,Georg Koller,Michael G. Ramsey,T. Greunz,David Stifter,Moritz Strobel,Sabine Hild,Achim Walter Hassel,Niyazi Serdar Sariciftci,Edward H. Sargent,Philipp Stadler +15 more
TL;DR: It is shown that the keto-amine hydrogen-bond motif enhances the rate-determining step in proton reduction to molecular hydrogen, and allows the demonstration of one week of continuous HER operation without notable degradation nor delamination from the carrier electrode.
