摘要 以钼酸铵和硝酸银为原料,采用一步水热法制备了不同形貌的纳米钼酸银(Ag2Mo2O7),探究了反应温度、反应时间、AgNO3浓度和表面活性剂聚乙烯吡咯烷酮(PVP)对产物结构及形貌的影响。利用X-射线衍射仪(XRD)、扫描电子显微镜(SEM)对纳米钼酸银的物相和形貌进行了表征。结果表明,通过改变水热反应条件可以得到纳米线、纳米棒、纳米片等不同形貌的钼酸银,其中反应温度和表面活性剂PVP对纳米钼酸银的形貌影响显著。

Abstract: Ammonium heptamolybdate and silver nitrate are used as raw materials to prepare nanocrystalline silver molybdate (Ag2Mo2O7) with different morphologies through one-step hydrothermal method.The effects of reaction temperature,reaction time,concentration of AgNO3 and surfactant polyvinylpyrrolidone (PVP) on the structure and morphology of Ag2Mo2O7 are investigated.The phase and morphology of Ag2Mo2O7 are characterized by X-ray diffraction (XRD) and scanning electron microscopy (SEM).Results show that silver molybdate with different morphologies such as nanowires,nanorods and nanosheets can be obtained by changing the reaction conditions.Of which,reaction temperature and PVP play the significant roles on the morphology of nano silver molybdate.
Key words:  Ag2Mo2O7    hydrothermal method    morphology    nanostructure
