Abstract: The research progress of alkali metal-based metal-organic frameworks (MOFs) in recent years is summarized in this paper. Alkali metal-based MOFs have attracted considerable attention due to their excellent performance in gas adsorption related field. In this review, the synthesis, structure, properties, and potential applications of alkali metal-based MOFs were introduced. Among them, the structure of the MOFs and the research on gas adsorption and storage including H₂ and CO₂ were emphasized and the gas separation and fluorescence detection were briefly reviewed. In addition, MOFs doped with alkali metal for H₂ sorption was also introduced. At the same time, the development trend of alkali metal-based MOFs was prospected.
