摘要
The mixed crystal nanometer TiO2 sonocatalyst was prepared by ultrasonic irradiation in hydrogen peroxide solution. The sonocatalytic activities were validated through the degradation of acid red B solution by ultrasonic irradiation in the presence of the title TiO2 catalyst. The results show that the sonocatalytic activity of the title TiO2 catalyst is obviously higher than that of original rutile and anatase nanometer TiO2 catalysts. The degradation ratio of acid red B in the presence of the title TiO2 catalyst surpasses 75%, while the degradation ratios are only 54.62% and 35.24% for rutile and anatase nanometer TiO2 catalysts, respectively.
