The present work is emphasized to develop novel ZnS/SnS/A-FA nanorods by using A-FA, ZnNO3.6H(2)O, SnCl2.2H(2)O and Na2S as precursor materials at ambient temperature. UV-vis DRS, PL, FE-SEM, EDX and TEM techniques were employed to confirm the formation of ZnS/SnS/A-FA nanorods. Photocatalytic activity of the ZnS/SnS/A-FA catalyst was checked under UV light using congo red dye as a model pollutant for waste water treatment applications. The results indicate that the fly ash incorporated ZnS/SnS have the capability to degrade the congo red dye within 150 min using 10 mg of the photocatalyst. The reuse property of ZnS/SnS/A-FA catalyst was appraised and was found to be quite stable during photocatalytic experiments. The pioneer antibacterial properties of ZnS/SnS/A-FA nanostructures were studied against gram-positive (Staphylococcus aureus) and gram-negative bacteria (Escherichia coli), which shows a significant antibacterial activity compared to ZnS/A-FA. ZnS/SnS/A-FA was proved as a potential material toward the wastewater treatment for the removal of dye molecules and pathogenic bacteria.
