Pathways to enhance electrochemical CO2 reduction identified through direct pore-level modeling

Sophia Haussener, Etienne Boutin, Evan Fair Johnson, Shuo Liu

Electrochemical conversion of CO2 to fuels and valuable products is one pathway to reduce CO2 emissions. Electrolyzers using gas diffusion electrodes (GDEs) show much higher current densities than aqueous phase electrolyzers, yet models for multi-physical ...

How Acid Washing Nickel Foam Substrates Improves the Efficiency of the Alkaline Hydrogen Evolution Reaction

Jan Van Herle, Suhas Nuggehalli Sampathkumar, Peter Hugh Middleton, Thomas Benjamin Ferriday

Nickel foam substrates are frequently utilised as porous 3D substrates for renewable energy applications. The preparation of these substrates usually includes an acid-washing step, but the degree to which this step affects the final electrochemical perform ...

Investigation of Ethylene and Propylene Production from CO2 Reduction over Copper Nanocubes in an MEA-Type Electrolyzer

Raffaella Buonsanti, Valery Okatenko

Previous work carried out in fully liquid environ-ments and at low current densities has demonstrated that highly uniform faceted copper nanocrystals display different selectivity profiles in CO2 reduction compared to polycrystalline copper. As part of ong ...

Crossover of liquid products from electrochemical CO2 reduction through gas diffusion electrode and anion exchange membrane

Andreas Züttel, Wen Luo, Jie Zhang

We reveal that a significant amount (>30%) of the liquid products from electrochemical CO2 reduction (CO2RR) in a flow reactor can cross the gas diffusion electrode (GDE) and anion exchange membrane (AEM). Crossover of volatile products through the GDE occ ...
