摘要：Recently, we reported the synthesis of highly crystalline Ag (Silver) spheres onZnOnanorods using Microwave Assisted Deposition-Precipitation (MADP) methodwith enhanced photocatalytic activity under visible light. In this paper, we report acomparative and experimental evidence for the potential applications of Ag/ZnOnanocomposites in waste water treatment. This paper presents the kinetics of Ag/ZnOtoward Methylene Blue (MB) degradation under UV and Visible light irradiation, andthe antibacterial properties toward Escherichia coli (E. coli) bacteria under light and inthe dark. Results indicate that the presence of silver nanoparticles on the surface of ZnOleads to a significant and simultaneous enhancement of the optical and photocatalyticdegradation efficiency of Ag/ZnO photocatalyst under UV and visible light irradiation,and was found to cause the inactivation of Escherichia coli (E. coli) bacteria undervisible light and dark. These results suggest that the presence of Ag nanoparticles play asignificant role in the photocatalytic activity and in the enhancement of the antibacterialactivity towards inactivation of Escherichia coli (E. coli) bacteria..
