Photocatalytic Degradation of Congo Red Dye Using Silver Doped TiO2 Nanosheets
TiO2 nanosheets were synthesized from tetrabutyl titanate precursor via solvothermal treatment using Hydrofluoric acid as structure directing agent. Anatase phase nanosheets could be obtained by this method, imparting good photocatalytic activity. In order to enhance photocatalytic activity, silver doping of TiO2 nanosheets was done using photo-deposition method under ultra-violet light irradiation. These nanosheets were characterized using Transmission electron microscopy, X-ray diffraction and Energy-dispersive X-ray spectroscopy. Photocatalytic activity was estimated by means of congo red dye degradation studies under ultra-violet light irradiation. The silver doped TiO2 nanosheets showed enhanced photocatalytic activity.
