Gas separation and detection technology is closely related to people’s daily production and life. With the emergence of various detection equipment, it has made remarkable progress in recent decades. Gas sensing materials play an important role in the process of gas separation and detection. Compared with traditional gas sensing materials, metal-organic frameworks (MOFs), as a new type of porous materials, has ultra-large surface area, extremely high porosity, regular pore structure and adjustable pore size. These unique advantages make MOFs particularly suitable as promising candidates for the gas pre-concentration, pre-separation and detection, so as to realize the collection and enhancement of low concentration gas, the separation of complex gas mixtures, and the reliable detection of trace target gases. The detection ability and separation efficiency are greatly improved eventually. Therefore, MOFs are expected to surpass the traditional materials, and their application in gas separation and detection deserves the attention of both academia and industry.

Key words: gas detection, metal-organic frameworks, gas preconcentrator, gas chromatographic column, gas sensor
