【摘要】 为了获得电化学性能优良的ZnMn₂O₄材料,以Zn（NO₃）₂和MnCl₂作为原料,以乙二醇作为溶剂,以Na₂CO₃作为沉淀剂,采用低温共沉淀法,制备得到微纳米颗粒堆积的ZnMn₂O₄粉体。通过XRD、SEM/TEM、BET、BJH、XPS等手段对所制备的ZnMn₂O₄样品进行结构表征。采用三电极体系,对样品进行了电化学性能测试。结果表明:所制备的ZnMn₂O₄样品属于介孔材料,比表面积可达95.8 m²/g,样品电极具有较好的电荷存储能力。研究结果可为电化学性能优良的ZnMn₂O₄材料的制备提供新的思路。更多还原

【Abstract】 To obtain ZnMn₂O₄ material with excellent electrochemical performance, ZnMn₂O₄ micro-nano particles were prepared by low temperature coprecipitation method, using Zn（NO₃）₂ and MnCl₂ as raw materials, ethylene glycol as solvent and Na₂CO₃ as precipitant. XRD、SEM/TEM、BET、BJH、XPS were employed to characterize the products obtained in detail. The electrochemical properties of the samples were tested with the three-electrode system. Results show that the ZnMn₂O₄ samples are mesoporous materials with a specific surface area up to 95.8 m²/g. The sample electrode has a certain charge storage capacity.The results can provide a new idea for the preparation of ZnMn₂O₄ material with excellent electrochemical performance.更多还原
