BET比表面积法在材料研究中的应用
|
摘要
BET表面积的测定方法是无机材料研究中最重要的实验工具之一。主要对BET吸附理论及BET公式、BET图分析、BET吸附等温曲线、BET测定法测定材料表面积的应用几个方面进行介绍。
BET is the specific surface area analysis,the main role is to determine the catalyst,the specific surface area of the carrier,and also can be used to test the surface area,pore structure and other properties of the material. The determination of BET surface area is one of the most important experimental tools in inorganic materials research. The application of BET adsorption theory and BET formula,BET diagram analysis,BET adsorption isotherm curve and BET determination method in the determination of surface area of materials were introduced.
