The CeO 2/TiO 2, SnO 2/TiO 2 and ZrO 2/TiO 2 composites were prepared by dispersing various nano-sized oxides (CeO 2, SnO 2, ZrO 2 and TiO 2) with ultrasound and mixing TiO 2 with CeO 2, SnO 2 and ZrO 2, respectively, in boiling water in a molar ratio of 4:1, followed by calcining temperature 500 °C for 60 min. Then a series of sonocatalytic degradation experiments were carried out under ultrasonic irradiation in the presence of CeO 2/TiO 2, SnO 2/TiO 2 and ZrO 2/TiO 2 composites and nano-sized TiO 2 powder. Also, the influences of heat-treatment temperature and heat-treatment time on the sonocatalytic activities of CeO 2/TiO 2, SnO 2/TiO 2 and ZrO 2/TiO 2 composites, and of irradiation time and solution acidity on the sonocatalytic degradation of Acid Red B were investigated by UV–vis spectra. It was found that the sonocatalytic degradation of Acid Red B shows significant variation in rate and ratio that decreases in order: CeO 2/TiO 2 > SnO 2/TiO 2 > TiO 2 > ZrO 2/TiO 2 > SnO 2 > CeO 2 > ZrO 2, and the corresponding ratios of Acid Red B in aqueous solution are 91.32%, 67.41%, 65.26%, 41.67%, 28.34%, 26.75% and 23.33%, respectively. And that the degradation ratio is only 16.67% under onefold ultrasonic irradiation. Because of the good degradation efficiency, this method may be an advisable choice for the treatment of non- or low-transparent wastewaters in the future.
