| 摘 要： | 采用液相沉淀法，通过选择不同起始原料并控制反应温度和pH值，制备得到不同形貌和结构的纳米BiVO4。采用X-射线衍射(XRD)、透射电子显微镜(TEM)和紫外-可见吸收光谱(UV-Vis)技术对产物进行分析表征。结果表明，采用NH4VO3作V源，室温下可直接制备得到结晶好的四方晶系硅酸锆型BiVO4球形纳米颗粒，提高反应液pH值或升高温度，可得到单斜晶系白钨矿型BiVO4，采用NaVO3作为V源，室温下可直接得到单斜晶系白钨矿型片状BiVO4。加入不同类型表面活性剂则得到不同形貌的BiVO4。 |

| Abstract: | The nano-sized BiVO4 with different morphologies and structures was synthesized by precipitation method through choosing different raw materials and controlling the reaction temperature and pH value. X-ray Diffraction (XRD), Transmission Electron Microscope (TEM) and UV-Vis absorbance spectroscopy were used to characterize the products. The results showed that highly crystalline tetragonal zircon-type structure of nano-sized BiVO4 with spherical particles was obtained at room temperature using NH4VO3 as the reactant. Monoclinic scheelite structure of BiVO4 was obtained through increasing the reaction temperature or the pH value. By choosing NaVO3 as the raw materials, monoclinic scheelite structure BiVO4 with a plate or rod-like shape was obtained directly at room temperature. BiVO4 with different morphologies was obtained when using different surfactants. |
