摘要：

通过设计包含催化剂制备、仪器表征和性质研究一体的综合实验，可以加深学生对催化化学的认识，使得传统理论催化教学更加立体化。本综合实验包括使用沉积-沉淀法制备CuO/TiO2催化剂，使用拉曼光谱对催化剂结构进行物相分析，以及评价该催化剂催化CO氧化反应的性能三方面内容，使学生建立起化学材料“结构-性能”之间的初步认识，提升科研实践能力，为今后科研之路奠定基础。

Abstract:

We design a comprehensive chemical experiment case, including catalyst preparation, instrumental characterization, and catalytic performance evaluation, to deepen students' understanding of the catalytic chemistry and make the traditional teaching on catalysis more stereoscopic. This experiment case involves the preparation of CuO/TiO2 catalysts by a deposition-precipitation method, the structure characterization of the catalyst by Raman spectroscopy, and the evaluation of the catalytic performance of CO oxidation reaction. From this experiment task, students can establish a preliminary understanding of the relationship of "structure-performance", improve the practice ability, and lay a foundation for future scientific research.
