M xCo3O4/g-C3N4 Derived from Bimetallic MOFs/g-C3N4 Composites for Styrene Epoxidation by Synergistic Photothermal Catalysis
Although metal-organic frameworks(MOFs) have been widely reported as precursors for obtaining various porous materials in recent years, the limited MOF types and monofunctional active site of MOF-based catalysts remain to be hard to crack. Herein, bimetallic MOFs, MCo-ZIFs stabilized by graphitized carbon nitride(g-C3N4) and their pyrolytic M xCo3O4/g-C3N4 hybrids(M=Zn, Cu, Fe, Ni) have been designedly synthesized. The obtained M xCo3O4/g-C3N4 hybrids display synergistic photothermal effect from both M xCo3O4 and g-C3N4 under visible light irradiation. Significantly, the solution temperature can be heated from room temperature(20 °C) to 66 °C after 40 min irradiation. Therefore, the catalytic activity of M xCo3O4/g-C3N4 exceeds those of most reported catalysts under mild reaction conditions. The optimal Zn xCo3O4/g-C3N4 catalyst realizes 96% conversion and 75% selectivity toward styrene oxide within 20 min. Incredibly, the Cu xCo3O4/g-C3N4 could achieve up to 89% selectivity toward styrene oxide. To our knowledge, this is the first report about the novel photothermal effect of ZIFs-derived metal oxides.
