The practical deployment of direct air capture (DAC) is hindered by insufficient mass and heat transfer, along with high energy consumption during regeneration, which are intrinsic drawbacks of conventional powdered amine adsorbents. To mitigate these bottlenecks, this work constructs a concentrated-light driven DAC system using a monolithic PEI/Ni/γ-Al₂O₃ adsorbents.
