Electrocatalytic Methanol Oxidation in a Gas‐Phase Electrolyzer: Formaldehyde versus Dimethoxymethane Formation

ChemElectroChem, Volume 13, Issue 11, 3 June 2026.
A gas‐phase electrolyzer with a Pt‐impregnated Nafion membrane anode was used for selectively oxidizing methanol to formaldehyde (FA) with low water content. However, maintaining the cell temperature at 100 °C for extended periods led to membrane dehydration and low water content in the effluent, causing most FA to react with methanol to form ...
