•Novel AgPO3 microspheres have been prepared successfully.•AgPO3 microspheres have showed high sonocatalytic activity.•The sonocatalytic ability has been explained in details. 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 radicals induced by AgPO3 microspheres under ultrasonic irradiation. The effects of other conditions on ultrasonic activity were also investigated. The content of OH radicals in the reaction system was determined to further verify the above conclusions.
