摘    要:通过添加十二烷基溴化氨(CTAB)利用液相沉淀法制备了不同形貌的纳米二氧化锰,用扫描电镜、X射线衍射、孔结构以及循环伏安法等分析研究了CTAB添加量对二氧化锰形貌和电化学性能的影响.结果表明,随着CTAB添加量的增加,二氧化锰形貌从长棒状到均匀球状发生规律变化,此外随着颗粒尺寸变小,二氧化锰比容量从162F/g提高到了...

关 键 词:二氧化锰  十二烷基溴化氨  共沉淀法  形貌

Abstract:A series of nanosized manganese dioxides have been synthesized via a co-precipitation process with additive of CTAB.SEM result indicated that with additive of CTAB,MnO2 nanosphere with about 20nm in diameter and a narrow particle size distribution has been obtained,comparable with nanorode morphology with a wide particle size distribution synthesized without CTAB.The adding amount of CTAB has been studied by SEM,XRD,N2 adsorption and desorption and cyclic voltammetric tests.The results found that as the dec...
Keywords:MnO2  CTAB  co-precipitation  morphology
