摘要: Abstract The electrooxidation of 2-chlorophenol (2-CP) on poly-nickel tetrasulfophthalocyanine (polyNiTSPc) modified glassy carbon (GC) and indium tin oxide (ITO) electrodes was studied by cyclic voltammetry in situ UV–Vis transmission spectroscopy. polyNiTSPc films were characterized XPS AFM, both before after reaction with 2-CP. results indicate that NiTSPc polymerizes at GC ITO electrodes, apparently retaining its phthalocyanine structure which the Ni atoms play a role similar to Ni(OH) 2 films. In oxidation 2-CP polyNiTSPc-modified electrode fouling layer polymerized products (polyCP) is weaker than bare electrode, probably because polyCP formed polyNiTSPc–ITO very rough, as indicated thus allowing passage CP molecules film.
