摘要
通过改变溶剂,利用氯化锌(ZnCl2)和三氯化铁溶液(FeCl3.6H2O)在140℃水热反应12 h,制备得到了Fe8(OOH)16Cl1.3,采用X射线衍射仪(XRD)和扫描电子显微镜(SEM)对产物的颗粒尺寸和形貌进行表征和分析.结果表明:反应溶剂分别为纯水→水/乙醇→水/乙二醇时,产物的颗粒尺寸变化为:250 nm→200 nm→100 nm.同时探讨了ZnCl2催化剂对产物尺寸的影响.
Fes (OOH)16Cl1.3was prepared by hydrothermal reaction of zinc chloride and iron chloride solution at 140℃ for 12 hours via changing the reaction solvent in the paper. The size and morphology of the product were characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM). The results showed that the product size was changing as this: 250 nm→200 nm →100 nm, when the reaction solvent was pure water→water/ethanol→water/glycol, respectively. Meanwhile, the influence of product's size with the use of zinc chloride catalyst was probed.
