摘要
以FeCl3.6H2O和CoCl2.6H2O为原料,以二次去离子水、聚乙二醇水溶液、丙三醇水溶液以及丙三醇/聚乙二醇水溶液为介质,采用水热法制备出CoFe2O4纳米粉体。利用XRD、FESEM对CoFe2O4纳米颗粒进行了分析,研究了不同反应介质对合成CoFe2O4颗粒结构和形貌的影响。结果表明,4种介质条件下均能生成尖晶石型CoFe2O4纳米颗粒。以二次去离子水和聚乙二醇水溶液为介质时,得到平均粒径为15 nm的球形CoFe2O4纳米颗粒;而以丙三醇水溶液及丙三醇/聚乙二醇水溶液为介质时,分别得到平均粒径为50 nm和100 nm的八面体颗粒。
Cobalt ferrite(CoFe2O4) nano-powder was prepared by hydrothermal method using FeCl3·6H2O and CoCl2·6H2O as raw materials in second deionized water,and its solutions with polyethylene glycol(PEG),glycerol,glycerol/PEG mixture in this article.X-ray diffraction(XRD) and field-emission scanning electron microscopy(FESEM) were used to investigate CoFe2O4 particles,and the effect of different reaction medium on the structure and morphology of CoFe2O4 was researched.The results show that spinel CoFe2O4 nanoparticl...
