Heavy is the Crown: Crown Ether Modulation of Cobalt Porphyrin CO2 Electroreduction in Zero‐Gap Electrolyzers

Angewandte Chemie International Edition, EarlyView.
The implementation of crown ethers into the ligand of cobalt porphyrins benefits the electrochemical CO2 reduction in the several ways: (1) the reduction potential is lowered in presence of K+; (2) it boosts the CO generation in Zero‐Gap Electrolyzers and (3) ensures complex stability during electrolysis.
