Abstract
ZnTiO3 nanoparticles and Ag-Fe co-doped ZnTiO3 nanoparticles were prepared using sol–gel method. The prepared samples were annealed at 700 °C and showed pure hexagonal ZnTiO3. All the samples were characterized by using X-ray diffraction (XRD), field-emission scanning electron microscope, energy-dispersive X-ray analysis, and UV analyses. The result showed that the hexagonal structure of Ag-Fe ZnTiO3 is affected with the increase in Ag-Fe concentrations. The zinc titanate nanoparticles were used for determining the degradation of cationic dye. Photocatalytic activity of ZnTiO3 nanoparticles was studied and compared with that of bare control. The results showed enhanced photocatalytic activity of the Ag-Fe co-doped ZnTiO3 compared to pure ZnTiO3, showing that the Ag-Fe co-doping deposition has a major function in enhancing the degradation capability of cationic dye.
