A kind of soluble planar binuclear metal-phthalocyanine was synthesized and was characterized by element analysis and FT-IR spectra. The effects of pH

concentration of catalytic agent and the various ratios of both binuclear phthalocyanineiron(Ⅲ) and phthalocyaninecobalt(Ⅱ) in mixtures on the catalytic oxidation of 2-mercaptoethanol were studied.The results showed that the catalytic activity of binuclear metal-phthalocyanine was the highest at pH=11 and the catalytic activity of binuclear phthalocyaninecobalt(Ⅱ) was higher than that of binuclear phthalocyanineiron(Ⅲ).Moreover

it was found that catalytic activity of binuclear phthalocyanineiron(Ⅲ) and phthalocyaninecobalt(Ⅱ) mixture was higher and even the best at the ratio of 1∶1

whose reaction mechanism was deeply discussed.
