The development of efficient direct air capture (DAC) systems coupled with photocatalytic CO₂ conversion is still an appealing challenge. Here, the authors engineered a series of defective Cu₃-based metal–organic frameworks (Cu₃-MOFs) for integrated atmospheric CO₂ capture and in situ photoreduction. The defective Cu₃-MOFs were constructed through selective removal of coordinated CO₃²⁻ from pristine MOFs with HCl etching, generating unsaturated Cu active sites for CO₂ harvesting, and the Cu₃-MOFs demonstrated enhanced CO₂ capture kinetics and capacity that compared to their pristine counterpart.
