Binuclear metallophthalocyanine supported on treated silk fibres as a novel air-purifying material

摘要

Two kinds of water-soluble metallophthalocyanines,binuclear phthalocyaninecobalt(II)(Co_2Pc_2)and binuclear phthalocyanineiron(III)(Fe_2Pc_2),have been investigated as catalysts for the oxidation of 2-mercaptoethanol (MEA).In aqueous solution,Co_2Pc_2 exhibited higher catalytic activity than Fe_2Pc_2at pH 11 and 25 deg C.Furthermore,synergistic effect had been found when two catalysts were mixed at molar ratio of 1:1,which was deeply discussed.To make best use of such perfect catalytic oxidation performance,a new supporting method was introduced to prepare the novel air-purifying material,binuclear metallophthalocyanine fibres (Mt_2Pc_2F).Mt_2Pc_2F could be used to eliminate efficiently the malodors of methanthiol and hydrogen sulfide by catalytic oxidation reaction.
