Effect Of Ag Doped On Phase Transformation, Morphology And Photocatalytic Activity Of TiO2 Powders
نویسنده
چکیده
The purpose of this research was to study the effect of doped Ag on phase transformation, morphology and photocatalytic activity of TiO2 powders. The composites powders were prepared by sol-gel method via calcinations at a temperature 400 °C for 2 h with a heating rate of 10 °C/min. The microstructure and crystallite size of TiO2 and TiO2-Ag powders were characterized by XRD, EDX and SEM. Finally, photocatalytic activity was evaluated by UV-vis spectrophotometer. The results show all samples have only anatase phase and the agglomeration. It was apparent that Ag added in TiO2 has significantly effect on photocatalytic reaction under UV irradiation. It can be noted that TiO2-5Ag powders was found to give the highest photocatalytic, 53% under UV.
