Crystalline and porous covalent organic frameworks (COFs) and metal-organic frameworks (MOFs) materials have attracted enormous attention in the field of photocatalytic II2 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 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 H-2 evolution under visible light irradiation. Especially, NH2-UiO-66/TpPa-1-COF (4:6) exhibits the maximum photocatalytic H-2 evolution rate of 23.41mmolg(-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.
