Sonocatalytic performance of Tb7O12/TiO2 composite under ultrasonic irradiation

► The sonotocatalytic properties of Tb7O12/TiO2 composite have been scarcely. ► A series of Tb7O12/TiO2 sonocatalysts were prepared through a simple method. ► The sonocatalytic activity of the as-synthesized samples is higher than that of pure TiO2 nanoparticles.
