| 英文摘要 | The controlled synthesis of Pd icosahedra in tetraethylene glycol with H2PdCl4 as a precursor and polyvinylpyrrolidone (PVP) as a stabilizer was demonstrated. Tetraethylene glycol served as both solvent and reducing agent, and uniform Pd icosahedra with a mean size of 45 +/- 5 nm were Successfully synthesized with a high yield of over 90% in oil-bath at 160 degrees C for 2.5 h. A certain affinity for the metal particles, a higher viscosity and a milder reducing power of tetraethylene glycol would be responsible for the formation of uniform and stable Pd icosahedra with a high yield. The optimum KOH/Pd(II) ratio, PVP/Pd(II) ratio, temperature, and heating time for the reaction system was 1.4/1, 1/1, 160 degrees C, and 2.5 h. respectively. (C) 2009 Elsevier B.V.
