Green and time-saving synthesis of MIL-100(Cr) and its catalytic performance

MIL-100(Cr) is an important member of metal-organic frameworks due to its large surface area, unique pore structure, good stability and unsaturated metal sites. Generally, this material was synthesized with the addition of HF and solvent for a long crystallization time (96 h). In this work, we report that MIL-100(Cr) can be synthesized under HF- and solvent-free conditions in a short crystallization time (15 h). The obtained MIL-100(Cr) possessed high surface area and rich porosity. Additionally, such material exhibited enhanced catalytic performance in the oxidation reaction of benzyl alcohol, demonstrating that it has potential applications in catalysis.
