Sonodegradation and photodegradation of methyl orange by InVO4/TiO2 nanojunction composites under ultrasonic and visible light irradiation

► A novel InVO4/TiO2 nanojunction composites were synthesized by an ion impregnate method. ► The (1:50) InVO4/TiO2 nanojunction composite showed highest sonocatalytic activity. ► The (1:25) InVO4/TiO2 nanojunction composite showed highest photocatalytic activity. ► The higher catalytic activity can be related to vectorial electrons and holes transfer.
