摘要:
通过水热法合成磁性Fe3O4@C/GQDs材料,然后采用共沉淀法负载不同含量的AgBr,合成 Fe3O4@C/GQDs/AgBr纳米复合微球; 通过TEM,XRD,FT-IR及BET等表征技术,表征材料物理化学性质。在可见光条件下测试纳米复合材料催化降解罗丹明B的光催化活性。研究表明:罗丹明B在3 h内降解率达到90%。
Abstract:
The Fe3O4@C/GQDs/AgBr nanocomposite microspheres were prepared by hydrothermal synthesis of magnetic Fe3O4@C/GQDs and then loaded with different contents of AgBr by coprecipitation method. The characterization techniques such as TEM, XRD, FT-IR and BET were used. The physical and chemical properties of the material were characterized. The photocatalytic activity of rhodamine B catalyzed by nanocomposites was tested under visible light conditions. Studies have shown that the degradation rate of rhodamine B reaches 90% within 3 h.
