中文摘要：
钼酸镍是重要的催化剂，其物相结构和形貌对催化性能影响较大。采用水热合成技术，借助络合助剂乙二胺四乙酸钠盐的形貌调控作用，在不同pI-I条件下制备了不同形貌的微，纳米钼酸镍。用X射线粉末衍射、透射电子显微镜和扫描电子显微镜对所得产物的物相结构、形貌和尺寸进行了表征分析，并对络合剂调控形貌的微观机理进行了初步探讨。结果表明，络合剂对钼酸镍微／纳米棒的形成起着关键作用。
英文摘要：
Nickel molybdate is an important catalyst, whose catalytic activity is subject to its phase structure and morphology. Micro/nano nickel molybdate with different morphologies had been successfully prepared via hydrothermal technique using c acid disodium salt dihydrate as shape-control agent under different pH,X-ray powder diffractometry, transmission electron microscope, and scanning electron microscope were employed for the characterization and analysis of the phase, morphology, and size of the resulting products.Results indicated that the complexation additive played a key role for the formation of micro/nano nickel molybdate rods.Corresponding micro mechanism of complexation additive controlling morphology was also preliminarily discussed.
