| 摘 要： | 四磺酸酞菁铜阴离子（ＣｕＰｃＴｓ＾４－）在水溶液中可借助离子交换进入阳离子表面活性剂双十二烷基二甲基溴化铵（ＤＤＡＢ）薄膜电极，从而形成ＣｕＰｃＴＳ＾４－－ＤＤＡＢ薄膜电极，循环伏安实验表明，在ＫＢｒ溶液中，该薄膜电极有一对良好的还原氧化峰，阴阳极峤电位分别为－０．７８Ｖ和－０．６５Ｖ（ｖｓ．ＳＣＥ）．探讨了该薄膜电极的电化学行为，特别是对其各种卤代乙酸的电化学催化，对其机理进行了推测。

| Abstract: | Copper phthalocyanine tetrasulfonate anion (CuPcTS 4- )in aqueous solutions could enter into the film electrode of cationic surfactant didodecyldimethyl ammonium bromide(DDAB)through ion exchange Cyclic voltammetric experiments showed that,in KBr solutions,the CuPcTS 4- DDAB film electrode had a stable pair of redox peaks The cathodic and anodic peak potentials were -0 78 V and -0 65 V ( vs SCE),respectively The electrochemical catalytic reduction of various halogenated acetic acids with this film electrode is described The mechanism of this catalytic reaction was postulated |
