| 摘 要： | 在以质子交换膜为隔膜的电解池内,通过3-甲基吡啶在PbO2/Ti、SnO2/Ti、石墨和MnO2/Ti电极上的电氧化研究发现,在硫酸溶液中,PbO2电极是催化活性最高的工作电极.通过3-甲基吡啶在硫酸、高氯酸、磷酸和乙酸介质中的电氧化研究发现,对于PbO2电极,硫酸是最适合的介质.利用循环伏安实验和恒电位电解实验,研究了电氧化条件和电催化活性,比较了各种条件下的电流效率和选择性.

| Abstract: | In an electrolytic cell with a 3-picoline at PbO2/Ti, SnO2/Ti, graphi proton exchange membrane, it was found from the electrooxidation of te 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 PbOJTi 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. |
