Abstract

Zn-doped NiFe₂O₄ was synthesized by using sol–gel citrate technique, and its phase homogeneity, surface morphology, optical, magnetic, and electrochemical performance were analyzed. X-ray diffraction (XRD) confirmed a cubic spinel structure with Fd3m space group symmetry. Field emission scanning electron microscopy (FE-SEM) revealed increasing agglomeration with Zn doping. Magnetic characterization via vibrating sample magnetometer (VSM) showed an increase in saturation magnetization with Zn content, specifying its soft magnetic behavior. UV-visible spectroscopy revealed an increase in bandgap energy from 1.7 to 3.89 eV with Zn doping. Current–voltage characteristics and voltage–time cycling data showed best conductivity for Zn composition x = 0.1. Impedance spectroscopy further indicated that charge transfer resistance was lowest for x = 0.1, measuring 50.23 Ω.

溶胶-凝胶柠檬酸法合成Ni1-xZnxFe2O4 （x = 0,0.1, 0.2, 0.3）铁氧体的多功能性能研究

采用柠檬酸溶胶-凝胶法制备了掺杂锌的NiFe2O4，并对其相均匀性、表面形貌、光学、磁性和电化学性能进行了分析。x射线衍射（XRD）证实了具有Fd3m空间群对称的立方尖晶石结构。场发射扫描电镜（FE-SEM）显示，掺杂Zn后，团聚现象增加。通过振动样品磁强计（VSM）进行的磁性表征表明，饱和磁化强度随Zn含量的增加而增加，表明其具有软磁行为。紫外可见光谱显示，掺杂Zn后，带隙能量从1.7 eV增加到3.89 eV。电流-电压特性和电压-时间循环数据表明，当锌成分x = 0.1时，电导率最佳。阻抗谱进一步表明，当x = 0.1时，电荷转移电阻最低，为50.23 Ω。
