Abstract: Cobalt phthalocyanine(CoPc)-didodecyldimethylammonium bromide (DDAB) surfactant film electrode could be prepared by casting the mixture of CoPc with DDAB chloroform solution on the surface of pyrolytic graphite electrode and then removing the chloroform by evaporation. Cyclic voltammetric experiments showed that the film electrode in KBr solution had a pair of well-defined and stable reduction and oxidation peaks at Epc=0.40 V and Epa=-0.36 V(vs. SCE),respectively.The electrochemistry of this system was studied and the electrochemical parameters were estimated. The CoPc-DDAB film electrode could be used to catalyze electrochemical reduction of halogenated acetic acids.

Key words: cobalt phthalocyanine, surfactant film, electrode, electrochemical catalysis
