摘要:

介绍了一个材料化学综合实验——SBA-16型介孔材料的制备、表面改性以及修饰。该实验将化学反应热力学、动力学以及表面吸附等相关物理化学理论知识与仪器分析相结合,学生不仅可以通过材料的制备过程了解材料形成的原理,还可以在材料的表征过程中学习X射线粉末衍射、透射电子显微镜、氮气吸附/脱附仪以及吸附重量分析仪等的使用方法,提升实验操作技能,培养学生解决问题的能力和创新意识。

关键词: 介孔材料, 表面改性, X射线粉末衍射, 氮气吸附仪, 化学综合实验

Abstract:

A new comprehensive experiment of material chemistry: the synthesis and characterization of SBA-16 mesoporous materials, and surface modification was introduced. This experiment combines the theory of thermodynamics, kinetics and surface adsorption, as well as instrumental analysis, which could improve the experimental skills, comprehensive and innovative abilities of the undergraduates. Based on this experiment, students can not only well understand the forming principle of mesoporous materials, but also learn the operation skill for XRD, N2 adsorption, TEM, Intelligent Gravimetric Analyzer, which could stimulate the interest in scientific research.

Key words: Mesoporous materials, Surface modification, X-ray powder diffraction, N2 physical adsorption, Comprehensive experiment of material chemistry
