| 摘 要： | 研究了一种制备Fe包Co空心微球的新方法.以纳米铁粒子为模板,水合肼为还原剂,通过化学镀制备出具有核-壳结构的Co包Fe纳米粒子,用HCl溶去Fe核制备出空心Co微球,以空心Co微球为模板,NaBH4为还原剂,通过化学镀Fe制备了亚微米Fe包Co的空心微球.研究发现,在化学镀Fe过程中,Fe包Co空心微球之间极易形成硬黏结,通过降低反应物浓度和反应温度,增大反应液pH值抑制镀液中Fe粒子的独立形核,则可明显防止Fe包Co空心微球之间硬黏结的发生.

| Abstract: | A new method to prepare Co hollow coated Fe microspheres is presented in this article.The Fe coated Co particles with core-shell structure were primarily synthesized by chemical reducing reaction using nano-Fe particles as a template and hydrazine hydrate as reducing agent and then hollow Co shell was prepared after dissolving Fe cores using HCl solution.Further,using hollow Co shell as a template and NaBH4 as reducing agent,Co coated Fe composite shell sub-micron hollow spheres were synthesized by chemical... |
