摘　　要：采用共沉淀法制备了AgBr/Ag_(2)CO_(3)复合催化剂。研究表明,AgBr/Ag_(2)CO_(3)复合催化剂的光催化性能比单一相的AgBr或Ag_(2)CO_(3)显著提高,0.10 g AgBr/Ag_(2)CO_(3)样品光照降解200 mL 10 mg/L的亚甲基蓝溶液20 min后,降解率高达99.97%,是AgBr的2.5倍,是Ag_(2)CO_(3)的4.77倍,且AgBr/Ag_(2)CO_(3)对亚甲基蓝的降解过程符合一级动力学模型。AgBr/Ag_(2)CO_(3) composite catalyst is prepared by co-precipitation method.The research shows that the photocatalytic performance of AgBr/Ag_(2)CO_(3) composite catalyst is better than that of single phase AgBr or Ag_(2)CO_(3).0.10 g AgBr/Ag_(2)CO_(3) composite catalyst is irradiated to degrade 200 mL of 10 mg/L Methylene Blue solution for 20 min,the degradation rate of Methylene Blue is as high as 99.97%,which is 2.5 times higher than that of AgBr and 4.77 times higher than that of Ag_(2)CO_(3).The degradation process of AgBr/Ag_(2)CO_(3) on Methylene Blue conforms to the first-order kinetic model.
