摘要：

Direct air capture (DAC) technology is a negative carbon technology, which is an effective supplement to the carbon capture, utilization and storage (CCUS) technology and one of the important technologies to help achieve the carbon peaking and carbon neutrality goals. Solid porous materials have irreplaceable advantages in reducing the economic cost and operating energy consumption of DAC due to their strong adsorption capacity, low regeneration energy consumption, flexible application scenarios and adjustable structure. Starting from the principles of DAC of solid porous materials, this paper focused on reviewing DAC adsorbents, such as zeolite adsorbents, silica-based adsorbents, carbon-based adsorbents, nano-alumina adsorbents, MOF adsorbents and porous resin adsorbents. The advantages and disadvantages on adsorption capacity, adsorption selectivity, hydrothermal stability, regeneration energy consumption and cycle stability of solid porous materials are introduced and compared. The effects of amine functionalization modification and carrier pore structure on the adsorption performance of CO2 are emphatically analyzed, and specific optimization directions for the challenges faced by various solid porous materials in the application of DAC are prospected. It is pointed out that the design and development of solid porous adsorbents in the future should take both economy and efficiency into account, and further pilot-scale DAC experiments should be carried out. © 2023 Chemical Industry Press.
