Electrochemical decarboxylation of acetic acid on boron-doped diamond and platinum-functionalised electrodes for pyrolysis-oil treatment
BDD electrodes decarboxylate acetic acid at 90% faradaic efficiency without competing OER, forming methanol and methyl acetate via hydroxyl radical reactions. Pt-modified BDD shifts selectivity toward ethane (Kolbe product), with thin Pt layers achieving >70% FE — offering a practical route for electrochemical acidity reduction in pyrolysis oil upgrading.
