稀土氢氧化镝纳米棒的水热合成及生长机理研究

本文介绍了一种水热合成稀土Dy(OH)3纳米棒的方法,反应条件温和,绿色环保,无污染.在水热过程中,以氧化镝粉末为反应前驱体,氢氧化钾为矿化剂,水为溶剂,180℃条件下水热48 h,合成了稀土Dy(OH)3纳米棒,再经过500℃热处理1h,即可得到同形貌的Dy2O3纳米材料.通过X射线粉末衍射(XRD)仪、透射电镜(TEM)对样品进行表征,结果表明,所制得的稀土Dy(OH)3为结晶良好、粒径均一、表面光滑的棒状纳米结构.同时,本文对矿化剂对产物形貌的影响进行了探讨.

Hydrothermal Synthesis and Mechanism Study of Dysprosium Hydroxide Nanorods

A facile and low-cost preparation of Dy(OH)3 nanorods was introduced in this paper.The Dy(OH)3 nanorods were prepared through hydrothermal method,which was maintained at 180 ℃ for 48 h.Dy2O3 powder was used as the precursor,and KOH was employed as the mineralizer.The reaction condition is mild,pollution-free and green environmental-protective.The X-ray diffraction(XRD) and transmission electron microscope(TEM) were employed to characterize the as-obtained low-dimensional nanostructures.The effects of mineralizer concentration and hydrothermal temperature on the morphologies of the products were also studied.
