Metal–organic frameworks (MOFs) have shown great promise for CO 2 capture and storage. However, the operation of chemical redox functions of framework substances and organic CO 2 ‐trapping entities which are spatially linked together to catalyze CO 2 conversion has had much less attention. Reported herein is a cobalt‐containing zeolitic imidazolate framework (Co‐ZIF‐9) which serves as a robust MOF cocatalyst to reduce CO 2 by cooperating with a ruthenium‐based photosensitizer. The catalytic turnover number of Co‐ZIF‐9 was about 450 within 2.5 hours under mild reaction conditions, while still keeping its original reactivity during prolonged operation.
