中文摘要：
本文选用不同沉淀剂，用共沉淀法制备了稀土储氧材料Ce0．65Zr0．35O2复合氧化物，对用不同沉淀剂制备出的氧化物样品进行了XRD，BET，OSC和H2-TPR的测试和分析。结果表明，用不同沉淀剂制备出的氧化物，均为立方相的铈锆固溶体，经1000℃ 5小时老化后也无相的分离；以（NH4）2CO3和NH3·H2O的混合物为沉淀剂制备出的氧化物有最大的比表面积，经600℃焙烧后高达120m^2／g以上；并且样品具有良好的储氧性能及低温还原能力。
英文摘要：
Ce0.65Zr0.35O2 complex oxides were prepared by the co -precipitation method using different precipitators, these complex oxides were characterized by X - ray diffraction, N2 loworption - desorpfion, oxygen - storage capacity and H2 temperature - programmed reduction. All these complex oxides were Ce0.75Zr0.25O2 cubic solid solution after calcinations under 600℃ for 4 hours, the specific surface area were 120m^2/g with the mixture of（ NH4 ）3 CO3 and NH3 · H2O for precipitators ,no new materials appeared calcinations under 1000℃ for 5 hours ; the sample has high oxygen storage capacity and low - temperature reduced capacities.
