To develop high-performance metal-organic frameworks (MOFs) for catalysis is of great importance. Here, we synthesized the mesoporous Cu 3− x Zn x (BTC) 2 (BTC = benzene-1,3,5-tricarboxylate) nanocubes in a deep eutectic solvent of ZnCl 2 /ethylene glycol solution. The route can proceed at room temperature and the reaction time needed is shortened to be 30 min, which is superior to the conventional solvothermal route that usually needs high temperature and long reaction time. The formation mechanism of the mesoporous Cu 3− x Zn x (BTC) 2 nanocubes in deep eutectic solvent (DES) was investigated by in situ synchrotron X-ray diffraction/small angle X-ray scattering/X-ray absorption fine structure conjunction technique. The mesoporous Cu 3− x Zn x (BTC) 2 nanocubes exhibit high catalytic activity and reusability for cyanosilylation reaction of benzaldehyde and aerobic oxidation reaction of benzylic alcohol.
