摘要
在物理化学实验教学的过程中融入科研进展,能增加化学、化工、能源、材料等相关本科专业课程的趣味性和创新性.催化领域目前研究的最前沿当属单原子催化,本实验秉承科教融合的理念,设计了一系列内容,包括氧化铁负载的铂单原子催化剂的制备、表征,以及单原子催化剂在硝基苯加氢反应中的性能探索.实验过程涉及多种仪器操作和分析手段,不仅能帮助学生掌握实验技能、巩固理论知识,更能激发学习热情、拓宽学科视野、提升综合素养.
Abstract
Integrating the latest research development into physical chemistry experiment teaching is an innovative method to improve the education quality,especially for undergraduates who major in chemistry,chemical engineering,energy,material,and so on.In this respect,single-atom catalysis,the frontier in catalysis field,is designed into teaching process as a new experiment.First,Fe2O3 supported Pt single-atom catalyst is easily prepared by co-precipitation method,and characterized via various advanced technologies.Moreover,the catalytic performance of Pt single-atom catalyst in hydrogenation of nitrobenzene is evaluated.Simultaneously,various aspects of students'abilities are enhanced,since a number of characterization technologies are involved in the multi-step experiment.As a result,this experiment can help students to master operation skills,consolidate knowledge points,inspire enthusiasm in studies,broaden scientific views,and eventually promote their comprehensive qualities.
