Ag–Pd and CuO–Pd nanoparticles in a hydroxyl-group functionalized ionic liquid: synthesis, characterization and catalytic performance

Author affiliations

Abstract

Heteronuclear Ag–Pd and CuO–Pd nanoparticles with a controllable Ag : Pd or Cu : Pd ratio were easily synthesized through thermal decomposition of their acetate salts in a functionalized ionic liquid, [C2OHmim][NTf2]. The structural and electronic properties of these particles were characterized by ICP-OES, TEM, XRD and XPS techniques. The Ag–Pd nanoparticles have a silver enriched core covered by a Pd enriched shell. The addition of Ag clearly enhanced the catalytic activity of Pd in the hydrogenation of –NO2 and –C[double bond, length as m-dash]C– functionalities. Interestingly, in the CuO–Pd nanoparticles, Pd tends to stay in the inner part of the particle, leaving the outer layer rich in CuO, which exhibits less activity than Pd NPs.
