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 ...
2023How 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 ...
MDPI2023Active sites on copper-based catalysts for electrochemical CO2 reduction selectively to C2+ products
Electrochemical CO2 reduction (eCO2RR) towards value-added chemicals, powered by renewable electricity, is a promising technology for storing the intermittent renewable energy in the form of chemical bonds. Among the various products of eCO2RR, multi-carbo ...
EPFL2022Evaluation Criterion of Proton Exchange Membrane (ECPEM) fuel cells considering inserted porous media inside the gas flow channel
Jan Van Herle, Hossein Pourrahmani
The focus of this study is to evaluate the effects of porous media inside the gas flow channel of Proton Exchange Membrane Fuel Cells (PEMFC) on four different output parameters of voltage, power density, pressure drop, and Nusselt number (Nu) considering ...
PERGAMON-ELSEVIER SCIENCE LTD2022New Insights into the Interface of Electrochemical Flow Cells for Carbon Dioxide Reduction to Ethylene
Shaik Mohammed Zakeeruddin, Jing Gao, Dan Ren
The implementation of an electrochemical flow cell has enabled improved efficiency for CO2 reduction. However, in situ spectroscopic insights into the interface are still lacking. Here, we investigate a series of copper layers with different thicknesses on ...
