| 摘 要： | 以Fe(NO_3)_3·9H_2O和Ni(NO_3)_2·6H_2O为原料,在未添加任何碱性沉淀剂和高温晶化处理的条件下,通过对实验条件(包括溶剂、溶剂热温度和时间)的优化,利用溶剂热法一步制备了具有良好结晶性和超顺磁性的NiFe_2O_4磁性纳米材料。结果表明:用H_2O和EtOH-H_2O做溶剂都不利于NiFe_2O_4的生成;用EtOH做溶剂,为了获得纯度较高的NiFe_2O_4磁性纳米材料,要保证适当的溶剂热温度和时间;所得材料的磁性能与材料中磁性组分NiFe_2O_4的含量和其结晶程度有关。该制备方法最突出的优点是简单、快速、成本低、从源头消除了污染,且所得的材料磁性能优良。

| Abstract: | Through optimizing the experimental conditions (including solvent, solvothermal reaction temperature and time), NiFe2O4 magnetic nanomaterial with good crystallization and super paramagnetic performance, was prepared by one-step solvothermal method using Fe(NO3)3·9H2O and Ni(NO3)2·6H2O as raw materials and EtOH as solvent without adding any alkaline precipitation agent or high-temperature crystallization process. The results show that the solvents, H2O and (H2O+EtOH), are disadvantageous to the target magnetic species NiFe2O4.Under the condition of EtOH as solvent, the proper solvothermal temperature and reaction time must be guaranteed in order to obtain NiFe2O4 magnetic nanomaterial with high purity. The magnetic properties of prepared materials are related to the content of NiFe2O4 and its crystallization degree. The prominent advantages of this preparation method are of simpleness, speediness, low cost, free pollution from the source and friendly-environment. And the prepared materials have excellent magnetic performance. |
