Two kinds of water-soluble metallophthalocyanine derivatives, binuclear phthalocyaninecobalt(II) (Co2Pc2) and binuclear phthalocyanineiron(III) (Fe2Pc2), were supported on cationic wool fibers (CWF) to obtain a novel air-purifying material, binuclear metallophthalocyanine fibers (Mt(2)Pc(2)CWF), and the optimal supporting conditions were pH 5,100 degrees C, and 60 min. Mt(2)Pc(2)CWF could eliminate efficiently the malodors of methanthiol and hydrogen sulfide at room temperature by catalytic oxidation reaction used oxygen in atmosphere as oxidant.
