摘要
负载型催化剂上的金属氧化物-氧化物界面由于其复杂的界面结构和合成难度而很少被研究.通过对合成温度、反应时间、表面活性剂-Ce源比例等实验条件的探索与优化,成功在Co3O4 纳米立方块表面制备出了具有均匀CeO2 覆盖状态的CeO2/Co3O4复合金属氧化物材料.所得材料的形貌结构、成分状态等物化性质通过扫描电镜、X射线衍射光谱、X射线光电子能谱等表征技术验证.为复合金属氧化物材料的可控合成制备提供研究思路.
Abstract
The metal oxide-oxide interface on supported catalysts has rarely been studied due to the complex interface structure and synthesis difficulty.The authors of this paper successfully prepared CeO2/Co3O4 composite metal oxide materials with uniform CeO2 coverage on the surface of Co3O4 nanocubes by exploring and optimizing experimental conditions such as synthesis temperature,reaction time,and surfactant-Ce source ratio.The physical and chemical properties of the obtained material,such as morphology,composition,and state,were verified through characterization techniques such as scanning electron microscopy,X-ray diffraction spectroscopy,and X-ray photoelectron spectroscopy.This work could provide research ideas for the controllable synthesis and preparation of composite metal oxide materials.
