Front Cover: Quantitative Analysis and Manipulation of Alkali Metal Cations at the Cathode Surface in Membrane Electrode Assembly Electrolyzers for CO2 Reduction Reactions (ChemSusChem 22/2024)

The Front Cover depicts an MEA electrolyzer as an ice wall, with penguins carrying CO2 through it, where it is reduced to C2+. The flow of K+ is represented by rain, and its variation is illustrated by the relationship between clouds and the sun. This illustration conveys a strong desire to address environmental issues by depicting penguins in Antarctica, which are severely affected by global warming, desperately reductions in the greenhouse gas CO2.
