Abstract: Gas adsorption on solid surfaces can be categorized into two types: physical adsorption and chemical adsorption. By applying knowledge of surface chemistry, this study aims to simulate and analyze experimental results in the resistive gas sensing process. The objective is to investigate the adsorption behavior and utilize it as research material for undergraduate innovation and entrepreneurship projects and undergraduate thesis designs. This research will enhance students’ understanding of gas-solid adsorption principles, improve their ability to apply theory to practice, and cultivate their scientific research skills.

Key words: Gas sensing, Gas-solid adsorption, Physical adsorption, Chemical adsorption, Charge transfer
