摘要 水热条件下,以双氧水和钼粉制备的过氧钼酸溶胶为钼源,乙醇为还原剂制备得到Mo O2纳米棒。利用X射线衍射(XRD)、扫描电子显微镜(SEM)以及场发射高分辨透射电子显微镜(HRTEM)对产物的结构与形貌进行表征。结果表明,水热反应初期过氧钼酸溶胶首先生成Mo3纳米带,随后在还原剂的作用下,纳米带逐渐劈裂成扇形Mo8O23,最后在乙醇的还原下,扇形Mo8O23纳米片进一步劈裂形成结晶良好的Mo O2纳米棒。 Molybdenum dioxide nanorods were prepared from peroxomolybdic acid sols via hydrothermal method. The morphology and structure of the samples were characterized by XRD,SEM and HRTEM. The growth mechanism of the Mo O2 nanorods was investigated by studying the influence of hydrothermal time on the structure and morphology of the products. Mo O2 nanorods were obtained by one-pot hydrothermal process using ethanol as a weak reducing agent,and the phase evolution of Mo O3nanobelts—Mo8O23nanosheets—Mo O2 nanorods was demonstrated by theoretical and experimental analysis.
