摘要
文章以氧化石墨烯(GO)为原料,通过溶剂热法制备钴铁氧体/还原氧化石墨烯复合材料(CoFe_2O_4/rGO)。利用透射电子显微镜(transmission electron microscope,TEM)、高分辨透射电子显微镜(high-resolution transmission electron microscope,HRTEM)、场发射扫描电子显微镜(field emission scanning electron microscope,FESEM)、X射线衍射仪(X-ray diffraction,XRD)等对其进行表征,并研究其对模拟有机染料废水的吸附性能。结果表明:所制备的CoFe_2O_4/rGO复合材料为具有核壳结构的球形纳米颗粒,其平均粒径约为180nm;CoFe_2O_4/rGO能高效吸附阴离子有机染料,对刚果红吸附量高达490.6mg/g,其吸附作用主要是由静电作用力引起的。
CoFe2O4/graphene(CoFe2O4/rGO)composites were synthesized via solvothermal method using graphene oxide(GO)as precursor.The synthesized composites were characterized by transmission electron microscope(TEM),high-resolution transmission electron microscope(HRTEM),field emission scanning electron microscope(FESEM)and X-ray diffraction(XRD),and their adsorption performances for organic dyes were also studied.The results indicate that a new type of core-shell structure CoFe2O4/rGO composites is successfully synthesized by solvothermal method,the average diameter of which is around 180 nm.The adsorption capacity for Congo Red(CR)is high to 490.6 mg/g.The composites can selectively remove anionic dyes from solution more effectively than cationic dyes owing to the electrostatic interaction.
