Abstract

A novel solution combustion and gel calcination process for the preparation of ZnO nanoparticles and ZnO/NiZnFe₂O₄ nanocomposites was introduced. The phase identification, morphologies and magnetic properties of ZnO nanoparticles and ZnO/NiZnFe₂O₄ nanocomposites were confirmed by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscope (TEM), vibrating sample magnetometer (VSM). The results showed that the concentration of zinc nitrate and the calcination temperature were two key factors for the grain size, crystallinity and properties of ZnO nanoparticles, while, the mass ratio of ZnO and NiZnFe₂O₄ in ZnO/NiZnFe₂O₄ nanocomposites was the important factor for the specific magnetizations () of ZnO/NiZnFe₂O₄ nanocomposites.

摘要

介绍了一种新颖的溶液燃烧和凝胶煅烧法来制备 ZnO 纳米粒子和 ZnO/NiZnFe₂O₄ 纳米复合材料。通过 X 射线衍射（XRD）、扫描电子显微镜（SEM）、透射电子显微镜（TEM）、振动样品磁强计（VSM）对 ZnO 纳米粒子和 ZnO/NiZnFe₂O₄ 纳米复合材料的物相、形貌和磁性能进行了确认。结果表明，硝酸锌的浓度和煅烧温度是影响 ZnO 纳米粒子粒径、结晶度和性能的两个关键因素，而 ZnO/NiZnFe₂O₄ 纳米复合材料中 ZnO 和 NiZnFe₂O₄ 的质量比则是影响 ZnO/NiZnFe₂O₄ 纳米复合材料比饱和磁化强度（）的重要因素。
