In our work, we employed a co-precipitation method to synthesize the silver doped tin oxide/Zinc Oxide Nano composites. This catalyst absorbs UV energy and in aqueous medium it degrades methylene blue dye. Scanning electron microscope (SEM) images were used to determine the surface morphology of Ag doped SnO2/ZnO. Characterization of the optical transmission (total and diffuse) was performed using FTIR analysis. XRD analysis was performed to determine the crystal structure. Raman analysis was used for the chemical structure of the NCs. In addition, photo catalytic activities were performed with the help of photo catalytic reactor chamber and UV spectroscopy for the degradation of the MB dyes.enDepartment of PhysicsSP20PhysicsphotocatalyticNanocompositesmchemical structureScanning electronDr. Ishrat SultanaThesis
