Materials for CO 2 capture have been extensively exploited for climate governance and gas separation. However, their regeneration is facing the problems of high energy cost and secondary CO 2 contamination. Herein, a reversed photosynthesis‐like process is proposed, in which CO 2 is absorbed in darkness while being released under light illumination. The process is likely supplementary to natural photosynthesis of plants, in which, on the contrary, CO 2 is released during the night. Remarkably, the material used here is able to capture 9.6 wt.% CO 2 according to its active component. Repeatable CO 2 capture at room temperature and release under light irradiation ensures its convenient and cost‐effective regeneration. Furthermore, CO 2 released from the system is successfully converted into a stable compound in tandem with specific catalysts.
