Resumen
This comprehensive experiment is specially designed for the third-year and above students who are majoring in chemistry, applied chemistry, and chemical engineering. Students conduct experiments in groups, which are required to synthesize the CeO2–NiTiO3/attapulgite (ATTP) composite catalyst by the sol–gel method; the resulting catalysts are further used in the research of low-temperature selective catalytic reduction (SCR) denitration to investigate the conversion rate of NOx, sulfur resistance, N2 selectivity, and stability of the catalyst. Through this comprehensive experiment based on research, students can have a full understanding of the characterization of the catalyst and master a basic analytical ability. Meanwhile, students are guided to realize the importance of environmental protection and understand how to use chemistry to carry out environmental restoration. Furthermore, in this comprehensive experiment, students’ experimental skill and the team spirit of cooperation are cultivated, which lay a solid foundation for the later graduation thesis.
