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 MoO 2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 Mo8 O 23,最后在乙醇的还原下,扇形 Mo8 O 23纳米片进一步劈裂形成结晶良好的MoO 2纳米棒。

Molybdenum dioxide nanorods were prepared from peroxomolybdic acid sols via hydrothermal meth-od.The morphology and structure of the samples were characterized by XRD,SEM and HRTEM.The growth mechanism of the MoO 2 nanorods was investigated by studying the influence of hydrothermal time on the struc-ture and morphology of the products.MoO 2 nanorods were obtained by one-pot hydrothermal process using eth-anol as a weak reducing agent,and the phase evolution of MoO 3 nanobelts—Mo8 O 23 nanosheets—MoO 2 nano-rods was demonstrated by theoretical and experimental analysis.
