摘要： 通过固相反应和 Kirkendall 效应制备了钼酸铁纳米管, 采用透射电镜、X 射线衍射、红外光谱和 X 射线光电子能谱对其进行了表征, 并考察了不同组成的钼酸铁纳米管催化分子氧氧化丙烯的性能. 结果表明, 具有纳米尺度 FeOx/MoO3 壳核结构的前驱物可以在比通常低得多的温度下发生固相反应生成钼酸铁纳米管, 其表面 Mo 物种富集, Mo 与 Fe 的相互作用较特殊. 用于丙烯选择氧化反应时其催化性能比通常的钼酸铁更好, 可生成环氧丙烷, 且选择性较高.

Abstract: Ferric molybdate nanotubes prepared based on the Kirkendall effect and solid state reaction show fairly high selectivity for propene oxide in the epoxidation of propene by air. The unique catalytic properties of the nanotubes could be responsible for the special interation between Mo and Fe on the nanotubes.
