| 摘 要： | 通过FeCl2.4H2O和FeCl3.6H2O混合共沉淀,合成平均粒径为6 nm和10 nm的Fe3O4纳米粒子。然后将两种Fe3O4纳米粒子分别与经HNO3氧化处理的多壁碳纳米管(MWCNTs)置于乙醇水溶液(水和乙醇的体积比为1∶1)中,在超声波作用下制备Fe3O4/MWCNT复合材料。用高分辨透射电子显微镜、X-射线光电子能谱、振动样品磁强计、X射线衍射仪、热重分析仪对所制备的Fe3O4/MWCNT复合材料进行表征。结果表明:由6 nm和10 nm Fe3O4纳米粒子所制备的Fe3O4/MWCNT复合材料中,Fe3O4的质量分数分别为26.65%和29.3%,相应的磁饱和强度分别为16.5 emug-1和7.5 emug-1。

| Abstract: | Iron oxide(Fe3 O4) nanoparticles with average sizes of 6 and 10 nm were synthesized by a chemical co-precipitation method from mixtures of FeCl2 · 4H2O and FeCl3 · 6H2O.They were ultrasonicated with HNO3-oxidized MWCNTs in a solution(water/ethanol=1∶1v/v) to carry out the decoration.The structure and properties of as-obtained Fe3 O4/MWCNT composites were characterized by transmission electron microscopy,X-ray photoelectron spectroscopy,vibrating sample magnetometry,X-ray diffraction and thermal gravimetry.Results showed that the Fe3 O4 mass fraction in the composites were 26.6 and 29.3 % for particle sizes of 6 and 10 nm,and their saturation magnetizations were 16.5 and 7.5 emu · g-1 respectively. |
