Abstract
In this work, the oxidation behaviour of phenol and chlorophenol contaminants present in the water catalyzed by histidine substituted nickel(II) phthalocyanine (NiPc) is reported. This work comprises synthesis, characterization and study the catalytic behaviour of histidine substituted NiPc on the oxidation of phenol and their substrates like 2- and 4-chlorophenols with 4-aminoantipyrine utilizing molecular oxygen. The products from the oxidation can be analyzed by UV-Vis spectroscopy and the results confirmed the formation of superoxide anion radical were crucial for the formation of product and a feasible mechanism including a successive transfer of single electron from phenolic compounds to O2 through the axis of histidine Ni(II)Pc was reported.
