Three-dimensional porous hollow fibre copper electrodes for efficient and high-rate electrochemical carbon dioxide reduction

PCS group publishes in Nature Communications!

Dr. Recep Kas, together with a team of researcher from the Inorganic Membranes group @UT and Leiden University, has recently evaluated the application of copper porous hollow fibers in electro-catalytic reduction of CO₂ to CO. The results of the research are now published in Nature Communications:

The quintessence of this paper is that the porous copper fibers allow very efficient mass transport of CO₂, protons, and CO to a large triple phase boundary where reactants and electrons meet. The result is a very high and spectacular efficiency: ~80-85% of the electrons is used for reduction of CO₂, around 75% of which result in CO formation, at exceptionally low over-potential.
