In this work, we successfully integrated two-dimensional (2D) COF with stable MOF. By covalently anchoring NH₂ -UiO-66 onto the surface of TpPa-1-COF, a new type of MOF/COF hybrid materials with high surface area, porous framework, and high crystallinity was synthesized. The resulting hierarchical porous hybrid materials show efficient photocatalytic H₂ evolution under visible light irradiation. Especially, NH₂ -UiO-66/TpPa-1-COF (4:6) exhibits the maximum photocatalytic H₂ evolution rate of 23.41 mmol g^-1 h^-1 (with the TOF of 402.36 h^-1 ), which is approximately 20 times higher than that of the parent TpPa-1-COF and the best performance photocatalyst for H₂ evolution among various MOF- and COF-based photocatalysts.1e:T43e,Solar energy-driven conversion of CO₂ into fuels with H₂ O as a sacrificial agent is a challenging research field in photosynthesis. Herein, a series of crystalline porphyrin-tetrathiafulvalene covalent organic frameworks (COFs) are synthesized and used as photocatalysts for reducing CO₂ with H₂ O, in the absence of additional photosensitizer, sacrificial agents, and noble metal co-catalysts. The effective photogenerated electrons transfer from tetrathiafulvalene to porphyrin by covalent bonding, resulting in the separated electrons and holes, respectively, for CO₂ reduction and H₂ O oxidation. By adjusting the band structures of TTCOFs, TTCOF-Zn achieved the highest photocatalytic CO production of 12.33 μmol with circa 100 % selectivity, along with H₂ O oxidation to O₂ . Furthermore, DFT calculations combined with a crystal structure model confirmed the structure-function relationship. Our work provides a new sight for designing more efficient artificial crystalline photocatalysts.
