Electrochemical CO₂ reduction in strongly acidic electrolytes 🧪
By Edan Bainglass

The study demonstrates that substantial (bi)carbonate precipitation occurs during electrochemical CO₂ reduction in Ag and Cu gas diffusion electrodes even in strongly acidic electrolytes (pH 1), correlating with a loss of selectivity for carbon products and increased hydrogen production. The manuscript provides experimental evidence that high local pH near the catalyst can lead to these issues, suggesting that sufficiently large current densities are needed to maintain high selectivity in acidic environments.
