Hydrothermal synthesis, magnetic and catalytic properties of peach-like Fe2(MoO4)3 micro-nano structure

  • 摘要: 以Fe(NO3)3和(NH4)6Mo7O24为反应物,在不添加表面活性剂的情况下,采用一步水热法成功地合成了一种新颖的钼酸铁(Fe2(MoO4)3)材料. 扫描电子显微镜和粉末X-射线衍射仪结果表明,所合成产品具有类桃形的微纳米结构,为单斜晶系结构材料,所用反应前驱物中的铁/钼投料比以及反应时间和温度等条件,对于形成Fe2(MoO4)3的层层紧密组装结构起到了关键作用,定向生长和层层自组装的纳米线构建了Fe2(MoO4)3的微纳米结构. 磁性能和催化性能测试结果表明,该Fe2(MoO4)3材料具有软磁性能,并在无光照的条件下对盐酸四环素(TC)表现出较好的催化降解效果,有望作为可磁性回收重复使用的TC降解催化剂.

     

    Abstract: Without adding any surfactant, the Fe2(MoO4)3 material is successfully prepared by the one-step hydrothermal method using Fe(NO3)3 and (NH4)6Mo7O24 as raw materials. Scanning electron microscope (SEM) and X-ray powder diffraction (XRD) results show that the synthetic products are monoclinic system materials and have peach-like hierarchical micro-nano structure. Several factors, including the Fe/Mo weight ratio, reaction time and temperature, play crucial roles in the formation of the Fe2(MoO4)3 layers of tightly packed structure, the oriented growth and layer-by-layer self-assembly of nano sheets are responsible for the formation of these micro-nano structure.Magnetic and catalytic experimental results reveal that the as-prepared Fe2(MoO4)3exhibits soft magnetic property and highly effective for the catalytic degradation of tetracycline hydrochloride (TC) in the absence of light irradiation, and is expected to be a promising catalyst of magnetic recycling reuse for TC degradation.
