文摘

A new composite (CCSs/MOFs) of carboxyl-rich carbon spheres (CCSs) and copper-based metal–organic frameworks (MOFs) was for the first time prepared. The CCSs/MOFs composite was synthesized by the coordinated growth of high surface area and porous MOFs, [Cu₃(BTC)₂(H₂O)]_n (HKUST-1), on the surface of the functionalized CCSs obtained through a one-step hydrothermal carbonization of glucose with acrylic acid at 180 °C for 24 h. The resulting composites showed a core/shell structure with a tunable diameter arranging from 0.6 to 3.0 μm, and possessed high specific surface area of 495 m2/g and nanoporous structures derived from MOFs. Further, the catalytic oxidation of benzylic alcohol to benzaldehyde as its application was studied.
