Abstract: The effects of acetone concentration and reaction temperature on the electrooxidation of 2-propanol at Pd electrode were investigated by cyclic voltammetry and chronoamperometry. The results show that acetone significantly poisons the electrocatalytic activity of Pd for 2-propanol oxidation. A competitive adsorption mechanism was proposed to interpret the poisoning effect.
