This study reports the facile synthesis and enhanced phototocatalytic performance of a novel ternary AgI/ZnO/α-Fe2O3 nanocomposite. The catalyst was prepared through cost effective hydrothermal and doping method. The photocatalyst was designed to overcome the limitation of pure ZnO ( limited visible light absorption) and the recombination rate of charge carriers. The efficiency was evaluated through the degradation of malachite green (MG), a toxic water pollutant, under visible light irradiation. The presence of non-degradable organic dyes, such as malachite green ( MG), in industrial waste water poses a significant threat to aquatic ecosystem and human health. Furthermore the degradation efficiency of the prepared AgI/ZnO/α-Fe2O3 was systematically investigated under optimized condition such as pH, light intensity, dose of catalyst, concentration of dye.
