TL;DR: Electrocatalytic reduction of CO2 over copper can be made highly selective by ‘tuning’ the copper surface with adsorbed organic molecules to stabilize intermediates for carbon-based fuels such as ethylene.
Journal ArticleDOI

TL;DR: In this article, an electrocatalyst with confined reaction volume by coating Cu catalysts with nitrogen-doped carbon layers was developed, which achieved an ethanol Faradaic efficiency of (52 ± 1)% and an ethanol cathodic energy efficiency of 31%.
Journal ArticleDOI
Continuous Carbon Dioxide Electroreduction to Concentrated Multi-carbon Products Using a Membrane Electrode Assembly
Christine M. Gabardo,Colin P. O’Brien,Jonathan P. Edwards,Christopher McCallum,Yi Xu,Cao-Thang Dinh,Jun Li,Edward H. Sargent,David Sinton +8 more
TL;DR: In this paper, a membrane electrode assembly (MEAMEA) electrolyzer was proposed to convert CO2 to C2+ products and then demonstrate an approach to release concentrated gas and liquid products from the cathode outlet.
Journal ArticleDOI
Combined high alkalinity and pressurization enable efficient CO2 electroreduction to CO
Christine M. Gabardo,Ali Seifitokaldani,Jonathan P. Edwards,Cao-Thang Dinh,Thomas Burdyny,Golam Kibria,Colin P. O’Brien,Edward H. Sargent,David Sinton +8 more
TL;DR: In this paper, a silver-based system that exhibits the lowest overpotential among CO2-to-CO electrolyzers operating at high current densities, 300 mV at 300 mA cm−2, with near unity selectivity was reported.
Journal ArticleDOI

TL;DR: Anion exchange membranes (AEMs) in zero-gap reactors offer promise in this direction; however, there remain substantial obstacles to be overcome in tailoring the membranes and other cell components to the requirements of CO2RR systems.
