摘要
通过超声化学法制备Fe2O3纳米粉体,研究了不同表面活性剂对纳米粉体的分散作用,同时也制备了掺杂不同离子的Fe2O3基纳米粉体;借助于XRD、TEM等测试手段对所制备的粉体进行了表征。结果表明:加入1%聚乙二醇2000对粉体有较好的分散作用。掺杂5%Al 3+后的Fe2O3纳米颗粒呈现出不规则多边形形貌,平均粒径为50nm。掺杂7%Sn4+后Fe2O3纳米颗粒的平均粒径减小到40nm。双相掺杂3%Al 3+和Sn4+可得到长轴90nm,短轴10nm的Fe2O3棒状颗粒。
Iron oxide nanoparticles were made by ultrasonic chemistry-method. Different kinds of surfactants has been used in order to studying their dispersant effect on the nanopowders. Iron ions doped Fee Oa nanopowders has been made in the experiment. The prepared powders were analyzed with the aids of SEM and XRD. Results were shown below. Adding lwt.%PEG2000 had a good effect on the powers＇ dispersivity. 5wt.%A13^＋doped Fe2O3nanopowders presented ir- regular polygon and its＇ size was 50nm. The average size of Fe20a nanopowders had been decreased to 4Onto after doping 7wt. %Sn4^＋, 3wt. %A13^＋ and an4＋ doped Fe2O3 nanopowders became clubbed with 9Onto long axis and 1Onto minor axis.
