摘要：

Gold clusters and nanoparticles were deposited on the three kinds of porous coordination polymers (PCPs), MOF-5, CIPIL-2, and Al-MIL53 by the solid grinding method. The size of Au particles depended on the kinds of PCPs and increased in the order of Al-MIL53 < CPL-2 < MOF-5. The mean diameter of Au particles supported on Al-MIL53 was estimated to be 1.6 nm by HAADF-STEM. Such small Au clusters on Al-MIL53 can catalyze one-pot synthesis of secondary amines from primary amines by sequential oxidation/hydrogenation owing to the remarkable improvement of hydrogenation efficiency of imine. Gold clusters deposited on Al-MIL53 can also promote N-alkylation of amine with alcohol to form a secondary amine under N-2 atmosphere without using O-2 and H-2.
