采用水(盐溶液)/AEO9+TX10/正辛醇/煤油微乳液体系,以FeCl3·6H2O 和硼氢化钠为反应物,在常温常压下制备铁纳米粒子。通过实验建立的拟三元相图确定了微乳液中各成分的最佳比例,并按此配成微乳液,制备出纳米粒子。通过TEM和XRD测试,证实产物为20 nm左右的球形纳米铁粒子,且粒度分布非常均匀。
Nanosized iron was prepared by reducing FeCl3·6H2O with NaBH4 in the micro?emusion of water(salt solution)/AEO9+TX10/octanol/kerosene at room temperature and atmospheric pressure. The pseudo?ternary phase diagrams were constructed. The optimum ratio of composition was determined. The structure and morphology of the prepared nanoparticles were investigated by means of X ? ray diffraction(XRD),transmission electron microscopy(TEM). The results show that the nanoparticles are spherical iron,with an average size of approximate 20 nm.
