多孔固体上的气体吸附是本科生化学或化学工程课程中经常讨论的主题。多孔固体上的孔隙率和气体吸附的概念通常通过使用市售设备记录的吸附等温线来讨论。这个讨论可能相当抽象，学生很难想象。此处，四个演示重点介绍了吸附剂上二氧化碳气体的吸附。这些简单的演示以动态方式展示气体吸附，可以帮助学生了解多孔固体的特性。
Gas adsorption on porous solids is a topic that is often discussed in an undergraduate chemistry or chemical engineering course. The idea of porosity and gas adsorption on a porous solid is usually discussed with adsorption isotherms recorded using commercially available equipment. This discussion can be rather abstract and can be difficult for students to visualize. Here, four demonstrations highlight the adsorption of CO2 gas on adsorbents. These simple demonstrations show gas adsorption in a dynamic way that can help students understand the properties of porous solids.
