Metal organic frameworks (MOFs) as semiconductor‐like materials, are considered to be promising photocatalysts for heterogeneous phtotocatalytic oxidation of styrene. Herein, copper‐based MOFs and titanium dioxide composite bifunctional photocatalyst (Cu–benzene‐1,3,5‐tricarboxylate‐titanium dioxide, Cu‐BTC‐TiO2) wereas synthesized, and the selective oxidation of styrene was achieved under mild conditions of oxygen and water. Cu‐BTC‐TiO2 nanoparticles (NPs) exhibited more than three times higher styrene conversion than Cu‐BTC and TiO2 individually under same condition, and the desired product benzaldehyde can be obtained with up to 82% yield. The improved performance may be attributed to the acid site of Cu‐BTC, which is conducive to the adsorption and activation of styrene. In addition, the formation of heterojunction between Cu‐BTC and TiO2 can regulate the band gap of photocatalyst, which is favorable for light absorption, and facilitate the separation, transportation and utilization of photogenerated electron holes. The present protocol features good functional group tolerance, mild reaction conditions, and the reusability of catalyst.
