  • 摘要: 通过水热及后续的热处理过程合成三维花状NiCo2O4材料，利用XRD，XPS和SEM对该材料的晶型、元素构成和表面形貌进行表征，并对其超级电容性能进行分析，结果表明：1）所合成的NiCo2O4材料结晶度不高.2）含有不同价态的Ni和Co元素，存在的两个氧化还原对Ni2+／Ni3+和Co2+／Co3+为赝电容的产生提供了两个活性中心.3）作为超级电容器电极材料，由纳米片组成的三维花状NiCo2O4材料表现出良好的超级电容性能.
    Abstract: Three dimensional flower-like NiCo2O4 was prepared by a hydrothermal method and annealing treatment. XRD, XPS and SEM were used to characterize the crystallization, element composition and morphology of synthesized material.The results showed that:1)The crystallinity of the synthesized NiCo2O4 material was not high. 2)The material contained Ni and Co elements with different valences. The presence of the Ni2+/Ni3+ and Co2+/Co3+ provided two active centers for the generation of pseudocapacitance. 3)As supercapacitor electrode material, the three dimensional flower-like NiCo2O4 displayed excellent electrochemical performance.
