Highly ordered hierarchical macroporous metal–organic framework (MOF) materials (macroporous MIL-125) have been successfully synthesized through a solvent evaporation-induced self-assembly route in one step. The obtained macroporous MIL-125 showed an extremely high specific surface area with the Brunauer–Emmett–Teller surface area reaching up to 1083 m2/g. Moreover, macroporous MIL-125 exhibited ordered hierarchical porous structure and excellent ultraviolet absorption ability. At present, atmospheric chemical fixation of CO2 is commonly used as a catalyst for noble metal materials, and few macroporous MOF materials are used for chemical fixation of CO2. Macroporous MIL-125 was used as the photocatalyst for atmospheric chemical fixation of CO2 and showed high cycle stability, good tolerance to substrates, and excellent yields of CO2 carbonylative coupling reactions under ultraviolet irradiation. These finding provides a novel route for chemical fixation of CO2 with photocatalysis through MOF materials.
