摘　　要：将最新的科研成果引进课堂代替陈旧的老实验有利于开阔学生的视野,激发学生的学习兴趣。本文介绍了一个以最新文献为基础设计的材料化学实验。该实验以乙二醇为溶剂、乙二醇和安息香为还原剂、PVP和Br-为盖帽剂制备超细Ag纳米线。通过该实验不但可以使学生掌握氮气保护装置、移液枪和高速离心机的使用,而且可以使学生进一步熟悉关于晶体结构的知识。Introducing the latest scientific research results into the classroom instead of the old experiments is beneficial to broaden students'horizons and stimulate students'interest in learning.This paper introduces a material chemistry experiment designed on the basis of the latest literature.Ultra-thin Ag nanowires were prepared by using ethylene glycol as solvent,ethylene glycol and benzoin as reductants,PVP and Br-as capping reagents.Through this experiment,students can not only master the use of nitrogen protection device,pipette gun and high-speed centrifuge,but also get familiar with the knowledge of crystal structure.
