金/金钯异质结纳米棒的合成及其催化性能研究——有关纳米催化的物理化学新实验设计与实践

Synthesis and Catalytic Effect of Au/AuPd Heterojunction Nanorods:Design and Practice of New Physical and Chemical Experiments on Nanocatalysis

基于金/金钯异质结纳米棒合成及其催化性能而开设物理化学的设计性实验,成功合成金/金钯异质结纳米棒并用于降解4-硝基苯酚。本实验将基础知识与科学前沿相结合,通过查阅文献、制定实验方案、处理和分析实验数据、撰写实验报告、制作和演讲PPT等,培养学生的学习能力、思考力、执行力、创新意识和科学精神。

In this paper,the synthesis of gold/(gold and palladium)heterojunction nanorods and the catalysis of 4-nitrophenol are introduced as a comprehensive and innovative experiment in physical chemistry specialty.Through this experiment which combined basic knowledge of physical chemistry and frontier sciences,undergraduates have mastered the abilities of consulting domestic and foreign literature,designing experimental contents and schemes,data processing and analysis methods,writing experiment reports,preparing PowerPoint slides and giving presentation.This innovative practice shows that this experiment is helpful to improve students’learning ability,thinking ability,execution ability,innovative consciousness and scientific spirit.
