摘要
该综合设计实验通过Ag物种的引进调控Ag-CeO2催化剂的界面形成,研究界面结构对催化剂表面微结构的影响,并揭示界面结构对Ag-CeO2催化剂催化性能的促进作用。该设计实验锻炼了学生的催化剂合成、结构和性能等方面实验技能,实验内容较新颖,紧跟当前科研生产实践前沿。通过该设计实验的实施,巩固学生的基本实验技能,学会运用基础知识分析和解释实验现象,增强学生的综合运用知识能力和科技创新意识,刺激学生的求知欲望与科研兴趣。
In this comprehensive design experiment,the interfacial structure of the Ag-CeO2 catalysts was adjusted through the introduction of Ag species.The microstructures of the catalyst samples are investigated to reveal the influence of the Ag-CeO2 interface formation on their surface microstructure and their catalytic performance.The comprehensive design experiment covers the preparation,structural characterization and catalytic performance evaluation of the Ag-CeO2 catalysts.The experiment content is relatively novel,and it closely follows the development frontier of the current scientific research and industrial production practice.Through the implementation of this comprehensive experiment,students are exercised in their experimental skills and learn to use basic knowledge to explain experimental phenomena,improve their comprehensive knowledge application ability and technological innovation awareness,and stimulate their desired knowledge and scientific research interest.
