In this paper, zinc tetraaminophthalocyanine (Zn-APc) was immobilized on cellulosic fiber by covalent bond to obtain a novel cellulosic fiber supported metallophthalocyanine, named Zn-TDTAPc-F. At pH 11, upon visible light irradiation for 6 h in the presence of O 2 , Zn-TDTAPc-F was found to be highly effective for the degradation of phenol in aqueous solution, and the degradation rate of phenol was more than 95%. HPLC was used to confirm formic acid, fumaric acid and maleic acid as its main degradation products.supported metallophthalocyanine catalyst, visible light, photo-degradation, phenol Phenolic compounds are typical hazardous and nonbiodegradable contaminants, which are commonly used as industrial chemicals and are by-products in many industrial productions. They can be found in the effluents of many industries, such as petroleum refining, petrochemicals, pharmaceuticals, organic chemicals manufacturing and printing, etc. The common treatment of these pollutants contains chemical oxidation, incineration, gasification, adsorption, biodegradation, solvent extraction, emulsion liquid membrane, etc. [1] However, these methods have the disadvantages of complicated operation procedures, high cost and low working efficiency, and it is urgent to develop a more suitable and eco-friendly method.Phthalocyanine compounds are widely used in many fields [2,3] because of their special properties, such as chemical stability, thermo, light, acid and alkaline resistance, and the application as effective catalysts [4][5][6] is of increasing interest. It was reported in literature that they were used as photosensitizers for the treatment of pollutants in wastewater [7,8] besides phenol compounds [9,10] due to their strong absorption in the range of visible light. While the small molecule phthalocyanines will enter into the environment to cause secondary pollution. Moreover, the efficiency of the catalyst is substantially affected by aggregation of the phthalocyanine complexes [11] .Cellulose is the most abundant natural organic polymer in nature, and the cellulosic fiber has some prominent advantages, such as its relatively low cost, high specific surface area and high stability, etc., so it is the preferable candidate as the support of the metallophthalocyanine catalyst.The efficiency of phthalocyanine complexes as photocatalysts for oxidation of organic compounds decreased because of its self-association, and phthalocyanine molecular cannot be recycled after treatment. To overcome the above disadvantages, a novel supported metallophthalocyanine, Zn-TDTAPc-F, was prepared by immobilizing zinc tetraaminophthalocyanine on cellu-
