摘要

在水溶液中, 常温常压下不加入任何催化剂, 用电子束加速器辐照作为一种新的方法可成功制备纳米镍. 利用X射线衍射 (XRD) 、透射电子显微镜 (TEM) 、激光衍射粒度分布仪 (LSPSDA) 、紫外可见光分光光度计 (UV) 、样品振荡磁力计 (VSM) 和差热分析仪 (DSC) 来分别表征材料的结构、形貌、大小、粒径分布、光学特征、磁学性能以及材料的熔点. TEM图像和LSPSDA分布图证明颗粒大小为39nm, 这与XRD实验通过Scherer理论公式计算的结果相一致.

Abstract

A new method, using electron beam, has been successfully developed to prepare nickel nano-particles at room temperature under ambient pressure, without any catalyst. The structure, morphology, size, size distribution, optical properties, magnetic properties and the melting point have been characterized by X-ray diffraction (XRD), laser scattering particle size distribution analysis (LSPSDA), transmission electron microscopy (TEM), ultraviolet-visible spectrophotometer (UV-vis), vibrating sample magnetometer (VSM) and differential scanning calorimeter (DSC), respectively. The LSPSDA and TEM results show that average size of the nickel nano-particles is about 39 nm, which is in agreement with the calculated value from XRD using Scherer formula.
