| 摘 要： | 以五水硝酸铋和五氧化二钒为原料,通过微波合成法制备了纳米BiVO4,采用X-射线衍射(XRD)、扫描电子显微镜(SEM)和透射电子显微镜(TEM)表征了样品的形貌、结构和特性。XRD表明所制备的样品是纯的单斜晶型BiVO4;SEM显示样品的形貌呈层状结构;TEM进一步指出这些片层结构是由小粒子聚集而成的多孔结构。以催化降解甲基橙来考察其光催化性能。在100mL的10mg/L甲基橙溶液中加入0.12g经673K恒温热处理2h后的BiVO4及0.2mL H2O2,调节pH值为3.0,在可见光下照射90min后,降解率达到94.70%,催化性能良好。 |

| Abstract: | The BiVO4 nanocrystalline was prepared with the bismuth nitrate pentahydrate and vanadium oxide as raw materials by microwave synthesis.The morphology,structure and properties of the product were characterized by X-ray diffraction(XRD),scanning electron microscopy(SEM) and transmission electron microscopy(TEM).The XRD result indicates that the prepared sample is pure monoclinic-type BiVO4,the SEM result shows that the morphology of the prepared sample is flake,and the TEM result further exhibits that the fl... |
