酞菁铁—表面活性剂薄膜修饰电极及其催化性能

将酞菁铁（ＦｅＰｃ）掺入阳离子表面活性剂双十二烷基二甲基溴化铵（ＤＤＡＢ）的氧仿溶液，并涂布于热解石墨电极表面，待氯仿挥发后即制得ＦｅＰｃ－ＤＤＡＢ薄膜电极，循环伏安实验表明，在ＫＢｒ溶液中该薄膜电极有２对还原氧化峰，第１对峰的Ｅｐｃｌ＝－０．６４Ｖ，Ｅｐａｌ＝－０．２９Ｖ（ｖｓ．ＳＣＥ）第２对峰的Ｅｐｃ２＝－１．０４Ｖ，Ｅｐａ２＝－０．９４Ｖ着重探讨了第２对峰的电化学行为，估计了该体系的电化学参

IRON PHTHALOCYANINE-SURFACTANT FILMMODIFIED ELECTRODE AND ITS CATALYTIC PROPERTIES

Iron phthalocyanine (FePc) - didodecyldimethylammocoum bromide (DDAB) surfactant film electrode could be prepared by coating the mixture of FePc with DDAB chloroform solution on the surface of pyrolytic graphite electrode and then leaving the chloroform evaporated. Cyclic voltammetric experiments showed that, in KBr solution, the Film electrode had two pairs of well -defined and stable reduction and oxidation peaks. For the first pair of peaks, Epcl=-0.64 V, and Epal= -0.29 V (vs.SCE), respectively, while for the second pair,Epc2= -1.04 V, Epa2=-0.94 V respectively. This paper studied the electrochemistry of the second pair emphatically. The electrochemistry of this system was studied and the electrochemical parameters were estimated. The FePc-DDAB film electrode could be used to catalyze electrochemcal reductionof halogenated acetic acide.
