摘要
采用溶胶凝胶法制备了YFeO3和超声分散法制备了YFeO3/TiO2-SnO2和YFeO3/TiO2复合物,通过酸性红B的声催化降解来评价复合材料的催化活性,并与单一TiO2的声催化性能进行了比较。结果表明,YFeO3/TiO2-SnO2的声催化活性明显优于单一TiO2或YFeO3/TiO2。并且考察了声催化剂的处理温度和用量,超声照射时间和染料初始浓度等因素对酸性红B降解率的影响。
YFeO3,YFeO3/TiO2-SnO2 and YFeO3/TiO2 composites were synthesized by the the sol-gel and the ultrasonic dispersion method,their sonocatalytic activities were evaluated through the sono catalytic degradation of acid red B,and sonocatalytic performance of ZnFe2O4/TiO2 and single TiO2 are compared.The results show that the ZnFe2O4/TiO2-La2O3 showed higher sonocatalytic activity than ZnFe2O4/TiO2 and single TiO2.Effects of preparation conditions such as sonocatalyst amount,heat-treated temperature,ultrasound irradiation time and dye original concentration on degradation rate of acid red B were examined.
