Crystalline and porous covalent organic frameworks (COFs) and metal‐organic frameworks (MOFs) materials have attracted enormous attention in the field of photocatalytic H 2 evolution due to their long‐range order structures, large surface areas, outstanding visible light absorbance, and tunable band gaps. In this work, we successfully integrated two‐dimensional (2D) COF with stable MOF. By covalently anchoring NH 2 ‐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 H 2 evolution under visible light irradiation. Especially, NH 2 ‐UiO‐66/TpPa‐1‐COF (4:6) exhibits the maximum photocatalytic H 2 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 H 2 evolution among various MOF‐ and COF‐based photocatalysts.
