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.
