The direct air capture (DAC) of CO2 is a promising strategy for decelerating the growing concentration of atmospheric CO2 to control global warming. However, DAC remains a grand challenge, calling for technologies with high CO2 capture capacity at ultra-low partial pressure (around 400 ppm) under humid conditions. Recently, metal-organic frameworks (MOFs) have been demonstrated as outstanding sorbents for gas capture and separation owing to their intrinsic porous properties. MOFs have been widely studied for CO2 capture from industrial gas mixtures, but DAC has more demanding recognition capacity, selectivity and efficiency requirements. In this review, we extensively summarize the current progress in designing MOFs for DAC at both laboratory and pilot scales, with specific attention to structure design strategies for enhancing CO2 capture at low partial pressures, and detailed discussion on efficient CO2/H2O capture selectivity or CO2-H2O co-capture at a molecular level. In addition, the thermodynamic process, design of a reactor for DAC via MOFs and related practical examination for pilot-scale studies are highlighted, and current challenges and prospects are elaborated upon.
