Abstract

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
