In contrast to the published reviews, this paper presents the current CO 2 capture technology and related adsorbents. Ī large number of relevant papers and reviews have been published. On the other hand, due to their high density of active sites, high stability, and rich topological structures, MOFs have distinct advantages, such as mild reaction conditions and easy adsorption and sequestration of CO 2. Through the modification of inorganic/organic nodes on functionality groups, the fine-tuning of the pore size and channel environment in MOFs can be precisely achieved, and then MOFs oriented to CO 2 capture can be synthesized. One is the modifiability of its secondary building units (SBUs) and organic ligands. Compared to traditional inorganic porous materials, MOFs have many advantages and show great application potential in CO 2 adsorption and sequestration. Adsorbents that can be used for CO 2 capture include activated carbon, zeolite, alumina, metal oxides (CaO, MgO, K 2O, Li 2O), metal-organic frameworks (MOFs), and other surface-modified porous media. In recent years, the development of carbon capture and separation (CCS) technology has attracted social attention. Therefore, it is urgent to work out an environment-friendly CO 2 capture technology to alleviate the greenhouse effect. Compared to other greenhouse gases, carbon dioxide (CO 2) has a weaker greenhouse effect, but it has the highest proportion in the atmosphere, with its warming effect accounting for about 60% of the total warming effect among all greenhouse gases. The Earth's climate is undergoing major changes characterized by global warming, according to numerous authoritative studies. Since the Industrial Revolution, the extraction and consumption of fossil fuels have caused a remarkable expansion of greenhouse gases in the atmosphere.
