摘要
为了引导化学专业本科生在大学化学实验中建立绿色化学的理念,设计了一个利用生物源壳寡糖衍生物来制备银纳米粒子的化学实验。该实验过程没有任何化学表面活性剂、稳定剂及模板的使用,具备绿色化学的基本要素。该实验能够在普通的化学实验室操作,尤其适合大学化学专业本科基础化学实验的课程设计。通过实验,能够让学生在熟悉纳米材料的合成、性能及表征的同时,亲身感受绿色化学的合成理念。
In order to guide the chemistry undergraduates to establish the green chemistry idea in the university chemistry experiment,a chemical experiment used biological source shell oligosaccharide derivative to prepare silver nanoparticles was designed.The experimental process did not have any use of chemical surfactants,stabilizers and templates,which had the basic elements of green chemistry.This experiment can be operated in ordinary chemistry laboratory,especially suitable for the course design of basic chemistry experiment of undergraduate majoring in Chemistry.Through experiment,students can be familiar with the synthesis,performance and characterization of nanometer materials,and feel the synthetic idea of green chemistry firsthand.
