Abstract As a desired utilization of the conversion CO 2 into valuable carbon fuel production under solar energy, it remains challenging due to lack efficient catalysts. Herein, 3D interpenetrating metal‐organic framework [Co(Tipa)(HCOO) (H O)]·H O (Co‐Tipa) with 1D open channel is solvothermally synthesized using semi‐flexible ligand (Tipa = tri‐(4‐(1 H ‐imidazol‐1‐yl)‐phenyl)amine). The tridentate bridge ligand‐oriented periodicity Co‐Tipa MOF combined ruthenium‐based photosensitizers mild reaction conditions form an nonhomogeneous co‐catalyst for photocatalytic reduction (CO RR). crystalline MOFs catalyst, rate, selectivity, and quantum yield visible light irradiation offer outstanding performance synergistic advantages structural feature, metal center, organic ligand. stability reusability in system are profited from robust entangled framework. mechanism how enhance RR assisted illustration through density functional theory (DFT) calculations. By leveraging unique properties MOFs, this study offers innovative approaches development more effective s catalysts that can selectively chemicals fuels.
