Garg, Sahil (author), Li, Mengran (author), Hussain, Tanveer (author), Idros, Mohamed Nazmi (author), Wu, Yuming (author), Zhao, Xiu Song (author), Wang, Geoff G.X. (author), Rufford, Thomas E. (author)We report a new strategy to improve the reactivity and durability of a membrane electrode assembly (MEA)-type electrolyzer for CO2 electrolysis to CO by modifying the silver catalyst layer with urea. Our experimental and theoretical results show that mixing urea with the silver catalyst can promote electrochemical CO2 reduction (CO2R),...journal article 2022

Assessing Silver Palladium Alloys for Electrochemical CO2 Reduction in Membrane Electrode AssembliesChandrashekar, S. (author), Geerlings, J.J.C. (author), Smith, W.A. (author)The field of electrochemical CO<sub>2</sub> reduction has been transitioning to industrially relevant scales by changing the architecture of the electrochemical cells and moving away from the traditional aqueous H-cells to membrane electrode assemblies (MEA). The reaction environments in MEAs vary drastically from that of aqueous H-cells,...journal article 2021

Blommaert, M.A. (author), Subramanian, S.S. (author), Yang, K. (author), Smith, W.A. (author), Vermaas, D.A. (author)Typically, anion exchange membranes (AEMs) are used in CO2 electrolyzers, but those suffer from unwanted CO2 crossover, implying (indirect) energy consumption for generating an excess of CO2 feed and purification of the KOH anolyte. As an alternative, bipolar membranes (BPMs) have been suggested, which mitigate the reactant loss by...journal article 2021

Ozden, Adnan (author), Wang, Y. (author), Li, Fengwang (author), Luo, Mingchuan (author), Sisler, Jared (author), Thevenon, Arnaud (author), Rosas-Hernández, Alonso (author), Burdyny, T.E. (author), Lum, Yanwei (author)CO <sub>2</sub> electroreduction offers a route to net-zero-emission production of C <sub>2</sub>H <sub>4</sub>—the most-produced organic compound. However, the formation of carbonate in this process causes loss of CO <sub>2</sub> and a severe energy consumption/production penalty. Dividing the CO <sub>2</sub>-to-C <sub>2</sub>H <sub>4</sub>...journal article 2021
