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pH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。

Abstract: 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 ethylenediaminetetraacetic 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. 

Key words: nickel molybdate, EDTA, special morphology, hydrothermal synthesis
