【摘要】 以硝酸银、碳酸钠为原料,通过共沉淀法获得Ag₂CO₃纳米粒,并以该纳米粒为前体化合物,采用原位离子交换法合成系列AgBr/Ag₂CO₃异质结可见光催化剂。采用XRD、SEM测定了抑制结的组成和形貌。同时考察了该催化剂在可见光下（λ>420 nm）的光催化降解盐酸莫西沙星性能。结果表明AgBr与Ag₂CO₃摩尔比为0.6时AgBr/Ag₂CO₃有最高的光催化活性,AgBr/Ag₂CO₃异质结光催化剂可有效提高Ag₂CO₃光催化剂降解盐酸莫西沙星的活性和稳定性。更多还原

【Abstract】 A series of AgBr/Ag₂CO₃ hybrids with visible-light responsive using Ag₂CO₃ via in situ anion-exchange method were obtained. The composites were characterized by means of XRD and SEM. The hybridized composites displayed highest photocatalytic activity for the photodegradation of moxifloxacin hydrochloride pollutant under visible-light irradiation when the composites with the proportion 0. 6 of AgBr to Ag₂CO₃. AgBr/Ag₂CO₃ hybrids can enhance the phtocatalytic activity and stability of Ag₂CO₃ for phtodegradation MX.更多还原
