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-射线衍射仪分析结果表明,所合成产品具有类桃形的微纳米单斜晶系结构,所用反应前驱物中的铁/钼质量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,并在避光条件下对降解盐酸四环素(TC)催化效果好,有望作为可磁性回收重复使用的TC降解催化剂.
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）3 exhibits soft magnetic property and highly effective for the catalytic degradation of tetracycline hydrochloride（ TC） in the dark,and is expected to be a promising catalyst of magnetic recycling reuse for TC degradation.
