A photocatalyst is generally defined as a material that induce chemical reactions in presence of light [1]. The efficiency of the photocatalyst is a function of the balance between charge separation, ease of interfacial electron transfer and energy-wasting charge recombination [2]. Organic pollutants especially dyes are the side-products from different manufacturing industries like as insecticides, paint and dye textiles and pharmaceutics. They are released into the the aquatic ecosystem and must be removed for environmental protection. TiO2 is an attractive material for numerous photocatalytic applications. The method of synthesis of TiO2 generally influences the photocatalytic activity of the catalyst. In this study we use adequate precursor for preparation of active TiO2 photocatalyst [3].
