摘　　要：对于多孔材料孔结构的表征,N_2吸附(77K)是最常用的方法。但随着多孔材料种类的日益丰富,CO_2吸附表征引起人们越来越广泛地关注。CO_2作为N_2吸附的有效补充,被用于各种传统和新型多孔材料的表征,特别是极微孔结构的探测。概述了CO_2吸附法表征多孔材料孔结构的现状,总结了CO_2吸附等温线的类型及测试条件,阐述了用CO_2吸附数据分析材料的比表面积、孔容和孔径分布时常见的各种问题。N2 adsorption is one of the most widely used methods to characterize the pore structure of porous materials. With the increasing variety of porous materials, more and more attention has been paid to CO2 adsorption. As an effective complement to N2 adsorption, CO2 has been used for the characterization of various conventional and novel porous materials, especially for the detection of extremely porous structures. The research status of characterization of porous structure with CO2 adsorption was introduced. The types and test conditions of CO2 adsorption were summarized, and common problems encountered in the analysis of the specific surface area, pore volume and pore size distribution of materials with CO2 adsorption data were discussed.
