反胶束微乳液法合成纳米SrTiO_3研究

The precursors of SrTiO3 were prepared by inverse micell microemulsion method. SrTiO3 nano-powders were synthesized by calcining the precursors at 800 ℃ in air for 4 hours and were characterized by XRD, IR, TG, SEM. The results show that the spherical SrTiO3 nano-particles have narrow distribution with an average size of 40 nm. The surfactants played an important role in controlling shape and size of nano-particles, and combined surfactants were more effective than single surfactant.

反胶束微乳液法制备的Fe_3O_4纳米微粒

报道了一种反胶束微乳法制备纳米Fe3O4微粒的方法。以十六烷基溴化铵／正丁醇／正辛烷／氨水构建反胶束微乳液体系，通过反胶束微乳法制备纳米Fe3O4微粒，利用X射线衍射（XRD）、红外光谱（IR）分析、透射电镜（TEM）等对所得产物进行表征和分析。结果表明，制备的产物为单相Fe3O4纳米微粒，粒径均匀，颗粒尺寸集中分布在20～30nm之间，纯度高，分散效果好。
