摘要

摘要: 采用溶胶凝胶法制备了纳米Ti1-xCexO2系列样品。利用X射线衍射（XRD）、透射电子显微镜（TEM）、高分辨电子显微镜（HRTEM）对纳米Ti1-xCexO2系列样品颗粒尺寸、形貌以及固溶区范围和物相组成进行了研究；同时，采用Rietveld结构精修的方法研究了Ce的不同掺杂量对TiO2晶体结构的影响。实验结果表明，Ce掺杂TiO2能够形成Ti1-xCexO2固溶体，Ti1-xCexO2的固溶区范围在x=0～0.06之间，Ti1-xCexO2的晶粒度为5～10 nm，平均颗粒粒度约35 nm，且粒度均匀。

Abstract: The series samples of Ti1-xCexO2 (x=0, 0.01, 0.02, 0.04, 0.06, 0.07 and 0.09) were prepared by Sol-Gel process. The particle sizes, morphologies, solid solution range and phase relations of Ti1-xCexO2 samples were studied by XRD, TEM and HR-TEM. Meanwhile, the Rietveld refinement method was employed to study the effect of Ce doped to crystal structure of TiO2. The results show that the solid solution of Ti1-xCexO2 can be formed by doping of Ce to TiO2, and x=0~0.06. The crystallization size of Ti1-xCexO2 is about 5~10 nm, its average particle size is about 35 nm, and they are uniform.
