The disposal of colored organic waste water from the textile industries causes serious problems to the aquatic ecosystem and because of this the aquatic environment is contaminated which created a serious threat to the living organisms. Textile industry is water-intensive resulting a large amount of harmful dye effluent 33. The increasing awareness on environment issues the norms are being specified by the governments of various countries 34. In view of complex chemical, molecular structures and inherent toxicity of the dyes, the complete removal of dyes from the effluent became difficult by conventional physico-chemical treatments like adsorption, coagulation and ion-exchange. Moreover, these treatments only transfer contaminants from one phase to another and fail to completely demineralize the toxic pollutants 35. The photocatalytic reaction has become a desirable method to convert the organic pollutants into simpler and harmless compounds to eliminate the environmental pollution 36. Therefore, it is highly desirable to develop a simple but effective way to degrade these colored organic wastes. Conventionally, a biological treatment or degradation process is utilized to decolorize the dyes, but it is ineffective for the complete removal and degradation of dyes. In last few years, the catalytic process derived by solar energy or other radiation energy has been studied for the successful degradation of harmful organic dyes into environmental friendly materials. Recently,
