Fabrication of a Highly Dispersed/Active Pd Nanoparticles Supported catalyst: a Cation-assisted Reduction Method in Ethylene Glycol-water Solution at Mild Temperature

Abstract

Development of sustainable routes for synthesis of precious metal supported catalysts is of great importance because of their wide applications in catalysis field. This paper reported a controllable and recyclable cation-assisted reduction route to fabricate palladium nanoparticles supported catalyst. At 323 K, the highly dispersed Pd/Al2O3-CARM was prepared through introducing M2+ (M = Mn, Zn or Cu) ions to promote the reduction of H2PdCl4 in ethylene glycol-water solution, and the residual filtrate after preparation could be recycled to prepare Pd/Al2O3 catalysts. A turnover frequency of 300 × 102 h-1 was provided on Pd/Al2O3-CARMn in solvent-free aerobic oxidation of benzyl alcohol to benzaldehyde.
