Preparation of ZnFe₂O₄ Nanometer Powders by Sol-Gel Method and Research about its Electrochemical Performance

Abstract:

The ZnFe₂O₄nanometer powders were prepared by EDTA sol-gel method. The samples were characterized by DTA, FT-IR, XRD techniques. The preparation process, the best heat-treatment temperature and the electrochemical performance had been studied. The results show that the spherical nanometer powders can be obtained and the best heat-treatment temperature is 900°C. The particle size is about 10nm and Ea is 0.88 eV.
