Abstract: The combination of theory and experiment, professional and subject frontier is a major trend in chemical engineering teaching. The research takes nickel oxide (NiO)/zinc oxide (ZnO) composite material as the research object, and explores the preparation of gas-sensitive materials, the assembly of gas-sensitive components, and the test and analysis of gas-sensitive performance. During the gas sensitivity test, the influence of temperature and target gas concentration on the gas sensitivity of the catalyst was investigated. The experiment is of moderate difficulty and closes to the frontier of science, allowing students to experience a comprehensive experimental process. In addition, this research combines theory and practice. Through the changes in the electrical properties of ZnO in different environments, students can truly understand the characteristics of chemical materials and the working principles of sensors, which is conducive to stimulating students’ interests in scientific research and cultivating students’ scientific research practical ability.
