Plasma-Activated Copper Nanocube Catalysts for Efficient Carbon Dioxide Electroreduction to Hydrocarbons and Alcohols
Dungfeng Gao,Ioannis Zegkinoglou,Núria J. Divins,Fabian Scholten,Ilya Sinev,Phillipp Grosse,Beatriz Roldan Cuenya +6 more
TL;DR: This work has developed highly active and selective copper nanocube catalysts with tunable Cu(100) facet and oxygen/chlorine ion content by low-pressure plasma pretreatments, demonstrating that the catalyst shape, ion content, and ion stability under electrochemical reaction conditions can be systematically tuned through plasma treatments.
Journal ArticleDOI
Influence of the support on surface rearrangements of bimetallic nanoparticles in real catalysts
TL;DR: Near-ambient pressure x-ray photoelectron spectroscopy is used to show that the surface rearrangement of bimetallic (rhodium-palladium) nanoparticles under working conditions for ethanol steam reforming with real catalysts is strongly influenced by the presence of a reducible ceria support.
Journal ArticleDOI
Enhanced Carbon Dioxide Electroreduction to Carbon Monoxide over Defect-Rich Plasma-Activated Silver Catalysts
Hemma Mistry,Hemma Mistry,Yong-Wook Choi,Alexander Bagger,Fabian Scholten,Cecile S. Bonifacio,Ilya Sinev,Núria J. Divins,Ioannis Zegkinoglou,Hyo Sang Jeon,Kim Kisslinger,Eric A. Stach,Judith C. Yang,Jan Rossmeisl,Beatriz Roldan Cuenya,Beatriz Roldan Cuenya +15 more
TL;DR: DFT calculations reveal that the defect-rich surface of the plasma-oxidized silver foils in the presence of local electric fields drastically decrease the overpotential of CO2 electroreduction.
Journal ArticleDOI
Selective CO 2 Electroreduction to Ethylene and Multicarbon Alcohols via Electrolyte-Driven Nanostructuring.
Dunfeng Gao,Ilya Sinev,Ilya Sinev,Fabian Scholten,Fabian Scholten,Rosa M. Arán-Ais,Núria J. Divins,Núria J. Divins,Kristina O. Kvashnina,Janis Timoshenko,Beatriz Roldan Cuenya +10 more
TL;DR: High C2+ selectivity of nanostructured Cu catalysts synthesized in the presence of specific anions can be attributed to the highly roughened surface morphology induced by the synthesis, presence of subsurface oxygen and Cu+ species, and the adsorbed halides.
Journal ArticleDOI
Operando Evolution of the Structure and Oxidation State of Size-Controlled Zn Nanoparticles during CO2 Electroreduction
Hyo Sang Jeon,Ilya Sinev,Fabian Scholten,Núria J. Divins,Ioannis Zegkinoglou,Lukas Pielsticker,Beatriz Roldan Cuenya,Beatriz Roldan Cuenya +7 more
TL;DR: A drastic increase in hydrogen production was observed for the Zn NPs below 3 nm, which is associated with the enhanced content of low-coordinated sites on small NPs, which can serve as guidance for the development of highly active and CO-selective Zn-based catalysts for CO2RR.
