Abstract

Abstract:

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.

Key words: Metal, Heterojunction nanomaterials, Synthesis, Catalytic performance, Comprehensive innovative experiment
