Semiconductor materials have always been an enduring research focus and play an important role in the development of science technology and economy. Amorphous SbVO4 nanoparticles were successfully prepared by a low-temperature aqueous solution chemical method. The morphology and elemental composition of SbVO₄ nanoparticles were analyzed by XRD, SEM, XPS and DRS. The semiconductor material was applied to the acoustic catalytic degradation of quinoline blue (QB). The effects of ultrasonic power, catalyst amount, initial dye concentration and pH value on the degradation rate were studied. In the solution of QB with different concentration (5∼20 mg/L), the efficiency of the degradation of amorphous SbVO₄ by acoustic catalysis was more than 97%. The acoustic catalytic degradation of QB by amorphous SbVO₄ nanoparticles was not restricted by pH. After four cycle experiments, the sonocatalytic degradation rate of amorphous SbVO₄ could still reach 83.97%. The possible sonocatalytic mechanism of SbVO₄ was proposed.
