Abstract

Silver doped TiO2 catalyst TiO2-Ag was synthesized by microwave hydrothermal method when the optimal condition was selected with orthogonal and single factor tests. The photocatalytic activity of TiO2-Ag catalyst was further enhanced by the microwave and ultrasonic assisted with using methyl orange as pollutants. And the TiO2-Ag was characterized by the XRD, SEM, EDS, TG-DSC-DTG, BET and ICP-AES. The results showed that the optimal conditions of TiO2-Ag prepared by microwave hydrothermal method was n(Ag+)/n(Ti4+)=0.003, microwave power 600 W, reacting time for 3 h at 140 and calcining time for 3 h at 550 . The TiO2-Ag had higher photocatalytic activity and stability which get better degradation efficiency in a relatively short period of time for the degradation of organic pollutants when the microwave and ultrasonic assisted optimization condition. The structure characterization of the catalyst showed that the microwave hydrothermal synthesis of Ag doped TiO2 photocatalysts had OH multi-surface, high crystallinity and large surface area, and inhibited the phase transformation of TiO2 from anatase to rutile. At the same time, the doped catalyst prepared by microwave hydrothermal process was feasible method with high rate the use of drugs.
