Effect of Different Electrode Materials and Different Acid Media on Electrooxidation of 3-Picoline

Abstract

Abstract:

In an electrolytic cell with a proton exchange membrane, it was found from the electrooxidation of 3-picoline at PbO₂/Ti, SnO₂/Ti, graphite and MnO₂/Ti electrodes that PbO₂/Ti is a electrode material with the highest catalysis activity in aqueous solution of sulfuric acid. It was found from electrooxidation of 3-picoline in sulfuric, perchloric, phosphoric and acetic acid media that sulfuric acid is a most satisfied medium for PbO₂/Ti electrode. The electrooxidation conditions and electrocatalytic activity were studied with cyclic voltammetry and potentiostatic electrolytic experiments, the current efficiency and the selectivity under various conditions were compared.

Key words: 3-Picoline; Nicotinic acid; Acid medium; Anode material; Electrooxidation, 3-Picoline, Nicotinic acid, Acid medium, Anode material, Electrooxidation
