Fabrication and sonocatalytic property of AgPO3 microsphere

AgPO3 microspheres were prepared by a simple hydrothermal method. The AgPO3 microspheres were characterized by X-ray powder diffraction (XRD), scanning electronic microscopy (SEM), Brunauer-Emmett-Teller (BET), UV-vis absorption spectroscopy (UV-vis), and photoluminescence (PL) measurement. SEM reveals that the AgPO3 microspheres were constructed by the accumulation of small particles. The as-prepared AgPO3 microspheres sonocatalytically degraded Rhodamine B (RhB) excellently under ultrasonic irradiation. The sonocatalytic ability results from the (OH)-O-center dot radicals induced by AgPO3 microspheres under ultrasonic irradiation. The effects of other conditions on ultrasonic activity were also investigated. The content of (OH)-O-center dot radicals in the reaction system was determined to further verify the above conclusions.
