Abstract

Abstract:

Experimental improvements on determining the specific surface area of solid samples have been made by preparing adsorbent materials (MCM-41), measuring N₂ adsorption-desorption isotherm and Origin software calculating the specific surface area through BET equation. These improvements enhance the students' understanding about the material synthesis, structure-property relationship, instrument operation and software data processing.

Key words: Specific surface area, Physical chemistry, Mesoporous materials, Adsorption
