摘要：
(Figure Presented) Flower power: A universal approach is presented for high-yield synthesis of Au, Pt, and Pd nanoflowers using the surfactant sodium N-(4-n-dodecyloxybenzoyl)-Lisoleucinate (SDBIL). The pH-dependent self-assembly using SDBIL is critical for nanoflower growth. The Pt and Pd nano-flowers show superior catalytic activity for Suzuki-Miyaura and Heck coupling reactions over spherical counterparts. © 2010 Wiley-VCH Verlag GmbH & Co. KGaA, Weinheim.
