摘要

Colloidal dispersions of polymer-protected Pd/Ag/Rh trimetallic nanoparticles were synthesized via self-organization by mixing colloidal dispersions of polymer-protected Rh nanoparticles with those of polymer-protected Pd/Ag bimetallic nanoparticles with a core-shell(Pd-core/Ag-shell)structure,which were prepared in advance by a sacrificial hydrogen-reduction method.The Pd/Ag/Rh trimetallic nanoparticles appeared to have a triple core-shell(Pd-core/ Ag-interlayer/Rh-shell)structure on the basis of UV-vis absorption spectra,FT-IR spectra of adsorbed CO,TEM,HR-TEM,and EF-TEM observation.The spontaneously formed trimetallic nanoparticles having an atomic composition of Pd/Ag/Rh = 1/2/13.5 and an average diameter of 2.2nm showed the highest catalytic activity among the metal nanoparticle catalysts tested here for hydrogenation of methyl acrylate at 30 °C under atmosphere of hydrogen.
