Ionic Liquid-Assisted Synthesis and Catalytic Properties of AuPd Bimetallic Particles.

ABSTRACT

Ionic liquid-assisted synthesis of inorganic materials has been demonstrated to be an efficient synthesis route in the inorganic community. Here AuPd alloy particles are successfully synthesized with the assistance of the ionic liquid 1-octyl-3-methylimidazolium chloride ([OMIM]Cl) at room temperature. The p-nitrophenol reduction reaction using the synthesized metal particles as the catalysts indicates that the synthesized Au(1)Pd(1) particles exhibit the highest catalytic activity in comparison with the studied AuPd particles, the Au and the Pd particles. Therefore, the present synthesis route could be used as an efficient synthesis strategy for fabrication of metal alloy particles with interesting catalytic properties.
