纳米Fe_3O_4/石墨烯的微波水热法制备与表征
|
摘要
为了增强氧化石墨烯的疏水性,采用微波水热法对氧化石墨烯进行改性,制备纳米Fe_3O_4/石墨烯复合材料。利用扫描电子显微镜(SEM)、透射电子显微镜(TEM)、X-射线衍射(XRD)、傅里叶红外光谱(FTIR)及热重分析(TG)对制备的材料进行了形貌、结构表征及成分组成分析。研究结果表明:Fe_3O_4/石墨烯复合材料中的Fe_3O_4纳米粒子粒径约为35 nm,分布均匀,尺度较均一,Fe_3O_4/石墨烯复合材料的分散性较好。
To enhance the hydrophobicity of graphene oxide( GO),the microwave hydrothermal method was used to modify GO,and the Fe_3O_4/graphene composites with hydrophobicity and strong adsorption were prepared. The morphologies and structures of Fe_3O_4/graphene were characterized by XRD,FTIR,SEM,TEM and TG. The results show that Fe_3O_4 nanoparticles of the Fe_3O_4/graphene composite were uniform and uniformly attached to the surface of the graphene. The size of Fe_3O_4 nanoparticles was about35 nm,and Fe_3O_4 nanoparticles were uniform distribution relatively.
