ZnO/graphene/TiO2 (ZGT) was synthesized by a simple solvothermal method. The as-obtained samples were characterized by X-ray diffraction, transmission electron microscopy and energy dispersive X-ray spectroscopy. The band gap energy of the as-synthesized catalysts were performed by UVevis diffuse re?ectance spectroscopy. The sonocatalytic activities of catalysts were tested by the oxidation of methylene blue, texbrite BAC-L, texbrite BBU-L and texbrite NFW-L under ultrasonic irradiation, and compared with ZnO/graphene (ZG), graphene, ZnO and TiO2, respectively. The results indicated ZGT displayed higher ultrasound activated sonocatalytic activity than other catalysts. The optimum conditions including irradiation time, pH, dye concentration, catalyst dosage and ultrasonic intensity were 12
