| 摘 要： | 以Bi(NO3)3·5H2O和NH4VO3为原料，采用一种新的低温固相法，通过控制研磨时间选择性制备高质量的单斜相BiVO4。并采用X-射线粉末衍射(XRD)，扫描电子显微镜(SEM)，傅立叶红外光谱(FTIR)和紫外-可见漫反射吸收光谱(DRS)技术对产物进行分析表征。同时，实验结果表明研磨时间、干燥时间和水含量对单斜相BiVO4的形成有很重要的作用。该方法具有合成温度较低，能耗较少，工艺简单，操作简便，环境友好等优点。最后，对低温固相法的机理进行了初步的探讨。

| Abstract: | Highly crystalline BiVO4 were prepared through a new low-temperature solid-state reaction (LSSR) by using Bi(NO3)3·5H2O and NH4VO3 as raw source and monoclinic BiVO4 can be selectively prepared via such a reaction by controlling rubbing time. The as-prepared BiVO4 particles were characterized by XRD, SEM, FTIR and DRS. Meanwhile, controlled experiments show that rubbing time, drying time and water content play important roles in the formation of monoclinic BiVO4. In addition, this method has advantages such as relatively low synthesis temperature, low power consumption, simple operation and environment friendly. Finally, the mechanism of LSSR has been primarily discussed. |
