| 摘 要： | 以SBA-15分子筛为载体,采用简单化学沉淀法制备Ni(OH)2/SBA-15分子筛复合材料,用X射线衍射仪、SEM、TEM和电化学工作站等手段研究复合材料的物相和超级电容性能.结果表明,硫酸改性的SBA-15分子筛比纯SBA-15分子筛具有更高的均一性,孔道发生显著变化,比表面积增大.Ni(OH)2/SBA-15复合材料的表面形貌为纳米尺寸的蜂窝孔状结构,活性材料Ni(OH)2由层状结构的-αNi(OH)2构成.电化学性能测试表明,Ni(OH)2/SBA-15复合材料的比容量随着放电电流密度的增大而降低,随着SBA-15分子筛在复合材料中所占质量分数的增大而降低.采用硫酸改性SBA-15分子筛制备的Ni(OH)2/SBA-15复合材料比采用纯SBA-15分子筛制备的Ni(OH)2/SBA-15复合材料具有良好的超级电容性能和动力学性能,材料最高比容量为1 069 F/g. |
