Visible‐light driven photoconversion of CO 2 into energy carriers is highly important to the natural carbon balance and sustainable development. Demonstrated here is the adenine‐dependent CO 2 photoreduction performance in green biomimetic metal–organic frameworks. Photocatalytic results indicate that AD‐MOF‐2 exhibited a very high HCOOH production rate of 443.2 μmol g −1 h −1 in pure aqueous solution, and is more than two times higher than that of AD‐MOF‐1 (179.0 μmol g −1 h −1 ) in acetonitrile solution. Significantly, experimental and theoretical evidence reveal that the CO 2 photoreduction reaction mainly takes place at the aromatic nitrogen atom of adenine molecules through a unique o ‐amino‐assisted activation rather than at the metal center. This work not only serves as an important case study for the development of green biomimetic photocatalysts used for artificial photosynthesis, but also proposes a new catalytic strategy for efficient CO 2 photoconversion.
