以硝酸亚铈和原钒酸钠为原料,采用水热和模板导向结合的方法制备出了晶形规整的钒酸铈纳米棒.探讨了模板剂,pH值和水热时间等因素对产物形貌和结构的影响,并用XRD,SEM,TEM等对产物的物相,结构和形貌进行了表征.结果表明,制备的产物为纯净的单一体心四方结构的钒酸铈纳米棒,其长度为12μm,径向尺寸分布为3050 nm.制备钒酸铈纳米棒的最佳工艺参数为:以EDTA为模板剂,水热温度为180℃,pH值为9,水热时间为24 h.模板剂,pH值和水热反应时间对制备CeVO4纳米棒有着非常重要的影响.EDTA的加入能够促进钒酸铈纳米微粒的形核;pH值影响粒子的聚集状态;水热时间的延长有利于制备结晶性能更好的钒酸铈纳米微粒 |

With cerium nitrate and sodium orthovanadate as raw materials, the cerium orthovanadate nanorods were synthesized successfully by a hydrothermal-template method. The as-prepared samples were characterized by X-ray powder diffraction(XRD), scanning electron microscopy(SEM), and transmission electron microscopy(TEM).And the influence of the different templates,pH values and hydrothermal time on the crystal and morphology of products were further studied. The results showed that the as-synthesized products were pure single-crystal of CeVO4 nanorods with body-centered tetragonal structure, the products consisted mainly of CeVO4 nanorods with length of 12 μm and diameter of 3050 nm, and the optimal parameters of the as-synthesized CeVO4 nanorods were: EDTA as a template, hydrothermal temperature of 180 ℃,pH value of 9 and hydrothermal time of 24 h.The parameters of templates,pH value, and hydrothermal time played a very significant impact on the synthesis of CeVO4 nanorods. The templates could promote the nucleation ability of cerium orthovanadate nanoparticles, and the pH value of the synthesis solution could affect the aggregation of the particles. With the extending of hydrothermal time the crystallity of nanoparticles would be more perfect |
