Abstract
Pure anatase TiO2 photocatalyst with different Ag contents was prepared via a controlled and energy efficient microwave assisted method. The prepared material was further characterized by several analytical techniques like X-ray diffraction (XRD), transmission electron microscopy (TEM), scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), surface area measurement (BET), Fourier transform-infrared spectroscopy (FT-IR), diffused reflectance spectroscopy (DRS), and thermogravimetric-differential thermal analysis (TGA-DTA). A 10Â nm average crystallite size with nano-crystals of pseudo-cube like morphology was obtained for optimal (0.25Â mol%) Ag doped TiO2. The present research work is mainly focused on the enhancement of degradation efficiency of methyl orange (MO) by doping of Ag in TiO2 matrix using UV light (365Â nm). A 99.5% photodegradation efficiency of methyl orange was achieved by utilizing 0.25Â mol% Ag doped TiO2 (1Â g/dm3) at pH=3 within 70 min. Recyclability of photocatalyst was also studied, with the material being found to be stable up to five runs.
