前沿科研成果融入材料合成与制备实验教学——氮掺杂碳基底负载单原子催化剂的制备

Integrating Frontier Scientific Research into Experimental Teaching of Material Synthesis and Preparation:Preparation of N-Doped Carbon-Based SACs

设计了一种制备氮掺杂碳基底负载单原子催化剂的本科生化学实验。首先,采用熔融盐法制备氮掺杂碳基底,然后,借助多孔材料对金属离子吸附性制备单原子催化剂。本实验能够使学生初步熟悉和掌握纳米材料的制备方法,掌握实验室基本仪器设备的使用,本实验操作简单、现象直观,可使学生体会物理化学实验的趣味性与科学性,激发学生科学研究的兴趣,提高学生的科学素养。

An undergraduate experiment was designed to prepare nitrogen doped carbon-based single atom catalysts.Firstly,nitrogen doped porous carbon was synthesis by salt melton method.Then,SACs were prepared for metal ion adsorption by means of porous materials.This experiment can exercise the students'ability to the preparation of nanomaterials,master the use of instruments and equipment.This experiment is simple in operation,and the phenomenon is intuitive,which can make students experience the interest and scientific nature of physical chemistry experiment,stimulate students'interest in scientific research,and improve students'scientific literacy.
