摘要：

Self-organization of metal nanoparticles, which is observed by mixing Ag nanoparticles and precious metal nanoparticles, is applied to the synthesis of Pd/Ag/Rh trimetallic nanoparticles having a Pd-core/Ag-interlayer/Rh-shell structure. These trimetallic nanoparticles work as a more active catalyst for hydrogenation of olefin than the corresponding monometallic and bimetallic nanoparticles.
