| 摘 要： | 以聚乙二醇(PEG)为软模板,采用水热法合成了尖晶石型NiFe2O4纳米晶,考察了PEG分子量对样品的影响,并对样品进行了X射线衍射,振动样品磁强计,扫描电镜,低温氮吸脱附和原子发射光谱表征.结果表明合成的NiFe2O4纳米晶具有尖晶石结构且粒度分布较为均匀.以PEG-400为软模板水热合成的样品粒度小、比表面积较大、饱和磁化强度较高;PEG-1500合成的样品粒度稍大、饱和磁化强度较高.

| Abstract: | NiFe2O4 nanocrystals were synthesized by hydrothermal method with polyethylene glycol(PEG) as a soft template.The effect of PEG molecular weight on properties of the sample was investigated.The samples were characterized by XRD,VSM,SEM,BET and ICP.The results show that as-synthesized NiFe2O4 nanocrystals with spinel cyrstal structure and uniformer particle distribution.The sample synthesized with PEG-400 as soft template has small particle size,higher specific surface and saturation magnetization;as-synthesized sample with PEG-1500 has larger particle size and higher saturation magnetization. |
