摘　　要：分别选用水热,浸渍,柠檬酸络合燃烧,共沉淀方法合成了多种前驱体,再经过600℃煅烧处理4 h,成功合成出纳米复合材料70%CeO2·30%NiO,对这些复合材料进行系统的XRD、BET、H2-TPR、O2-TPD表征和CO催化氧化性能测试.In this paper, hydrothermal synthesis, impregnated method, citric acid complexation- combustion method and co - precipitation method were initiated to prepare 70% CeO2 ·30% NiO precursors. Then, the synthesized precursors were subjected to calcination at 600 ℃ for 4h, respectively. The gained nonocomposites were characterized by XRD, BET, H2-TPR, 02 -TPD and their catalytic properties were evaluated by CO oxidation.
