摘要：Pd-1-Au-1 l bimetal catalysts supported on basic layered double hydroxide (LDH) have been prepared conveniently with surface impregnation methods and structurally characterized by XRD, TEM and XPS. The nanoparticles were highly dispersed on LDH with an average size of 2.08 +/- 0.3 nm and showed a strong cooperative effect between Au and Pd for the step of the alcohol oxidation. Moreover, the present hydrotalcite-supported bimetal catalysts can catalyze efficiently one-pot alpha-arylation reactions of nitriles with various alcohols in aqueous phase through tandem reactions. The bimetal catalyst has been extended for a broad substrate scope and recycled for at least 4 times. (C) 2014 Elsevier B.V. All rights reserved.
