以(CH2OH)2和H2O的混合溶液为溶剂, Ce(NO3)3?6H2O和In(NO3)3?4.5H2O分别为Ce和In源, 采用溶剂热法在200 ℃下合成了前驱体, 再经500 ℃焙烧2 h制备了In3+掺杂的CeO2粉末. 通过研究一系列In3+的添加浓度, 得出In3+掺杂CeO2中In3+溶度为1% (摩尔分数). In3+掺杂对CeO2形貌的影响不大, 溶In3+前后的CeO2颗粒形貌均为层状结构, 但当In3+的添加量高于溶度时, 出现了细碎的第二相颗粒. In3+饱和掺杂浓度时CeO2粉末的比表面积高于未掺杂的CeO2, 达到100 m2/g, 当In3+的添加量大于等于3%时比表面积有所下降. In3+添加量对储氧能力的影响为: 首先, In3+的引入能够明显降低CeO2的低温还原峰温度; 其次, 当In3+的添加量为饱和浓度1%时, CeO2的低温储氧能力由未掺杂的3.6×10-4 mol/g提高到4.4×10-4 mol/g; 当In3+的浓度大于等于3%时, 试样的低温储氧能力先有所下降, 随后趋于稳定. 不同In3+添加量CeO2粉末的晶格常数、氧空位浓度、比表面积和低温储氧能力都在1% In3+溶度的位置出现了转折. 低温储氧能力与比表面积和氧空位浓度都有关联, 是二者综合作用的结果.
