Front Cover: Benchmarking the Electrochemical CO2 Reduction on Polycrystalline Copper Foils: The Importance of Microstructure Versus Applied Potential (ChemCatChem 21/2022)

Abstract

The Front Cover shows five polycrystalline copper surfaces, with differing microstructural features, on which the electrochemical CO2 reduction reaction is performed. In their Research Article, R. Kortlever and co-workers benchmark the electrochemical CO2 reduction reaction on five commercial polycrystalline copper foils. A thorough characterization of these foils show that they possess different microstructural features, such as grain sizes, crystallite sizes, micro-strains and crystallographic orientations. However, the study finds that the CO2 reduction performance of these foils is very similar. The obtained results stress the importance of the applied potential as a dominant factor controlling the electrocatalytic performance, outperforming microstructural effects in polycrystalline copper foils. More information can be found in the Research Article by R. Kortlever and co-workers.
