通过两步水热法,在泡沫镍基底上成功制备了NiMoO4-CoMoO4纳米复合材料.借助X射线衍射仪(XRD)研究材料的晶格结构,利用扫描电子显微镜(SEM)及其X射线能谱仪(EDS)研究材料的表面形貌和元素组成.在2 mol/L的KOH电解液中,采用三电极体系对NiMoO4-CbMoO4纳米复合材料进行循环伏安、恒电流充放电、交流阻抗和循环充放电测试,分析电极的电化学性能.结果 表明NiMoO4-CoMoO4复合电极具有良好的电化学性能和循环稳定性:在1 A/g的电流密度下,材料的比电容为219.8 F/g,经过1000次循环后,比电容保持率为101.3%.所合成的NiMoO4-CoMoO4纳米复合材料为未来高性能超级电容器电极材料的选择提供了参考,也必将具有良好的应用前景.
