摘要: 采用水热合成法,通过改变反应条件与表面活性剂的种类、添加量、铁源等,制备了具有不同形貌的Fe2O3超细粒子,并利用扫描电镜与X射线衍射仪等对Fe2O3粒子的形貌和尺寸及晶型结构进行了观察.研究表明:反应温度、反应时间、pH值和反应物添加量的比例等都会影响Fe2O3粒子的形貌和尺寸,通过调控添加剂种类等实验条件,获得了片状、立方体状、汉堡状、梭子状、长方体状、核桃状、六棱柱状、中空状等Fe2O3粒子的不同形貌,实现了对α-Fe2O3超细粒子形貌的可控制备.

Abstract: A series of the iron oxide particles with different morphology were prepared by changing the hydrothermal synthesis conditions, type and addition amount of surfactant. The morphology, size and crystal form of the iron oxide particles were characterized using scanning electron microscopy and X-ray diffraction measurement. The results showed that the reaction temperature, reaction time, pH value and reactant amount could affect morphology and size of the iron oxide particles. The iron oxide particles with sheet-like, cubic, burger-like, shuttle-like, rectangular, walnut-like, hexagonal prism and hollow morphology can be obtained by adjusting the additive type and other experimental conditions. The controllable preparation of the iron oxide particles with different morphology is realized.

Key words: iron oxide, superfine particles, hydrothermal method, morphology, controllable preparation
