Xinyi Chen,Xinyi Chen,Junfeng Chen,Nawal M. Alghoraibi,Danielle A. Henckel,Ruixian Zhang,Uzoma O. Nwabara,Uzoma O. Nwabara,Kenneth E. Madsen,Paul J. A. Kenis,Paul J. A. Kenis,Steven C. Zimmerman,Andrew A. Gewirth,Andrew A. Gewirth +13 more
TL;DR: In this paper, a Cu-polyamine hybrid catalyst was developed through co-electroplating, which significantly increased the selectivity for ethylene production, achieving a Faradaic efficiency of 87% and full-cell energy efficiency of 50%.
Journal ArticleDOI
Durable Cathodes and Electrolyzers for the Efficient Aqueous Electrochemical Reduction of CO2
TL;DR: The need for research into high performing and durable CO2RR systems is stressed by summarizing the state-of-the-art with respect to durability and proposing a protocol for standard durability testing of CO2 RR systems.
Journal ArticleDOI
Controlling Speciation during CO2 Reduction on Cu-Alloy Electrodes
Xinyi Chen,Xinyi Chen,Danielle A. Henckel,Uzoma O. Nwabara,Uzoma O. Nwabara,Yuanyuan Li,Anatoly I. Frenkel,Tim T. Fister,Paul J. A. Kenis,Andrew A. Gewirth,Andrew A. Gewirth +10 more
TL;DR: In this paper, the authors used 3,5-diamino-1,2,4-triazole (DAT) as an electrodeposition inhibitor to obtain a high surface area Cu-based catalyst.
Journal ArticleDOI
Investigation of Electrolyte-Dependent Carbonate Formation on Gas Diffusion Electrodes for CO2 Electrolysis.
TL;DR: In this paper, the degradation of gas diffusion electrodes (GDEs) in a flowing, alkaline CO2 electrolyzer via the formation of carbonate deposits on the GDE surface was investigated.
Journal ArticleDOI
Potential Dependence of the Local pH in a CO2 Reduction Electrolyzer
Danielle A. Henckel,Michael J. Counihan,Hannah E. Holmes,Xinyi Chen,Xinyi Chen,Uzoma O. Nwabara,Uzoma O. Nwabara,Sumit Verma,Joaquín Rodríguez-López,Paul J. A. Kenis,Andrew A. Gewirth +10 more
TL;DR: In this article, the local pH of a gas diffusion electrode undergoing CO2 reduction is quantified, owing to a multitude of competing processes, both electrochemical and transport-related.
