Journal ArticleDOI
Operando Insight into the Correlation between the Structure and Composition of CuZn Nanoparticles and Their Selectivity for the Electrochemical CO2 Reduction.
Hyo Sang Jeon,Janis Timoshenko,Fabian Scholten,Ilya Sinev,Antonia Herzog,Felix T. Haase,Beatriz Roldan Cuenya +6 more
TL;DR: The evolution of the Cu–Zn interaction with time during CO2RR was found to be responsible for the change in the selectivity from CH4 over Cu-ZnO NPs to CO over CuZn alloy NPs.
Journal ArticleDOI
Operando Investigation of Ag-Decorated Cu2O Nanocube Catalysts with Enhanced CO2 Electroreduction toward Liquid Products
Antonia Herzog,Arno Bergmann,Hyo Sang Jeon,Janis Timoshenko,Stefanie Kühl,Clara Rettenmaier,Mauricio Lopez Luna,Felix T. Haase,Beatriz Roldan Cuenya +8 more
TL;DR: In this paper, a well-defined Cu2 O nanocubes (NCs, 35-nm) uniformly covered with Ag nanoparticles (5 nm) were synthesized.
Journal ArticleDOI
Selectivity Control of Cu Nanocrystals in a Gas-Fed Flow Cell through CO2 Pulsed Electroreduction.
Hyo Sang Jeon,Janis Timoshenko,Clara Rettenmaier,Antonia Herzog,Aram Yoon,See Wee Chee,Sebastian Z. Oener,Uta Hejral,Felix T. Haase,Beatriz Roldan Cuenya +9 more
TL;DR: In this paper, the authors compared the CO2RR selectivity of Cu catalysts subjected to either potentiostatic conditions (fixed applied potential of -0.7 VRHE) or pulsed electrolysis conditions (1 s pulses at oxidative potentials ranging from Ean = 0.6 to 1.5 VRHE).
Journal ArticleDOI
Steering the structure and selectivity of CO2 electroreduction catalysts by potential pulses
Janis Timoshenko,Arno Bergmann,Clara Rettenmaier,Antonia Herzog,Rosa M. Arán-Ais,Hyo Sang Jeon,Felix T. Haase,Uta Hejral,Philipp Grosse,Stefanie Kühl,Earl M. Davis,Jing Tian,Olaf M. Magnussen,Beatriz Roldan Cuenya +13 more
TL;DR: In this paper , a pulsed reaction protocol consisting of alternating working and oxidizing potential periods that dynamically perturb catalysts derived from Cu 2 O nanocubes was used to decouple the effect of the ensemble of coexisting copper species on the product distribution.
Journal ArticleDOI
Size effects and active state formation of cobalt oxide nanoparticles during the oxygen evolution reaction
Felix T. Haase,Arno Bergmann,Travis E. Jones,Janis Timoshenko,Antonia Herzog,Hyo Sang Jeon,Clara Rettenmaier,Beatriz Roldan Cuenya +7 more
TL;DR: In this article , the authors used operando X-ray absorption spectroscopy and density functional theory calculations to provide quantitative near surface structural insights into oxygen-evolving CoO x (OH) y nanoparticles by tracking their size-dependent catalytic activity down to 1 nm and their structural adaptation to OER conditions.
