摘要
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1 h,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。
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.
