摘要:
为寻找一种绿色高效的纳米CeO2制备方法,采用葡萄糖-尿素低共熔体系作为溶剂,一步法制备出纳米CeO2并使用NaCl作为阻隔剂提高其分散性。采用X射线衍射、扫描电子显微镜、透射电镜等表征手段对材料进行表征测试。结果表明:所制备的纳米CeO2均为球形,粒径分布2~9 nm。随着NaCl添加量的增加,CeO2的粒径、分散性及比表面积均呈现先增加后减少的趋势,当硝酸铈与NaCl的质量比为1∶3时,CeO2-5粒径最小为2.51 nm,比表面积最大为75 m2/g,分散程度最好。因此,合适的NaCl添加量有利于分散的纳米CeO2形成。

Abstract:
To develop a green and facile method for nano CeO2 preparation, a eutectic system of glucose-urea was used as a solvent to prepare nano CeO2 by a one-step method and NaCl was used as a barrier to improve its dispersity. X-ray diffraction, scanning electron microscopy, transmission electron microscopy and other methods were used to characterize the materials. The results revealed that the morphology of nano CeO2 is spherical, with a particle size distribution of 2-9 nm. And the particle sizes, dispersity and specific surface area increase first, then decreases with the increase of NaCl addition. When the mass ratio of erium?nitrate and NaCl is 1∶3, the minimum particle size of CeO2-5 is 2.51 nm, the maximum specific surface area is 116 m2/g, and its dispersion degree is the best. Therefore, the appropriate amount of NaCl is conducive to the formation of dispersed nano CeO2.
