【 摘 要 】

Visible-light-active Ag2CO3nanoparticles were synthesized by a simple sonochemical method (ambient temperature for only 1 h). The effects of ultrasound pulse mode, ultrasound time and pH value on the photodegradation properties of Ag2CO3were investigated. The samples were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray (EDS), UV-vis diffuse reflectance spectroscopy (DRS) and nitrogen adsorption-desorption techniques. The photocatalytic activity was evaluated by degrading methylene blue (MB) under visible light irradiation (λ>420nm). According to obtained results, it was found that MB degradation (about 99.4% after 20 min of irradiation) was higher compare to conventional stirring method, which might be due to the higher specific surface areas and active sites. The method described here can be used to improve the efficiency of visible-light sources and develop an ecologically friendly, practical wastewater treatment for pollutants.
