AB - Here, we propose the use of hydroxyacetone, a dehydration product of glycerol, as a platform for the electrocatalytic synthesis of acetone, 1,2‐propanediol, and 2‐propanol. 11 non‐noble metals were investigated as electrode materials in combination with three different electrolyte compositions toward the selectivity, Coulombic efficiency (CE), and reaction rates of the electrocatalytic hydrogenation (formation of 1,2‐propanediol) and hydrodeoxygenation (formation of acetone and propanol) of hydroxyacetone. With a selectivity of 84.5 %, a reaction rate of 782 mmol h−1 m−2 and a CE of 32 % (for 0.09 m hydroxyacetone), iron electrodes, in a chloride electrolyte, yielded the best 1,2 propanediol formation. A further enhancement of the performance can be achieved upon increasing the educt concentration to 0.5 m, yielding a reaction rate of 2248.1 mmol h−1 m−2 and a CE of 64.5 %. Acetone formation was optimal at copper and lead electrodes in chloride solution, with lead showing the lowest tendency of side product formation. 2‐propanol formation can be achieved using a consecutive oxidation of the formed acetone (at iron electrodes). 1‐propanol formation was observed only in traces.
