Abstract:	摘要： Seed nanoparticles of silver, platinum, and palladium (typically ≤4 nm in diameter) were prepared using tetrakis(hydroxymethyl)phosphonium chloride (THPC) as the reducing agent and utilized to generate pure silver, platinum, and palladium nanoshells, along with hybrid platinum/silver nanoshells, on silica cores. The sizes, size distributions, morphologies, chemical compositions, and optical properties of the THPC-metal nanoparticles (THPC-mNPs) were characterized by transmission electron microscopy (TEM), selected area electron diffraction (SAED) analysis, X-ray photoelectron spectroscopy (XPS), Fourier transform-infrared (FT-IR) spectroscopy, and ultraviolet-visible (UV-vis) spectroscopy. Characterization of the resulting nanoshells was performed using scanning electron microscopy (SEM), TEM, and UV-vis spectroscopy. While the use of THPC-gold nanoparticles to seed metal nanoshells is well known, the process is time consuming and requires highly concentrated seeding solutions. Our THPC-mNPs were used to seed the growth of a variety of metal nanoshells in rapid fashion, including the successful generation of highly uniform platinum and palladium nanoshells grown from their own seeds. Efforts to optimize our nanoshell syntheses produced expedited procedures for generating metallic shells with continuous, smooth surfaces. Seed nanoparticles of Ag, Pt, and Pd (typically ≤4 nm in diameter) were synthesized using tetrakis(hydroxymethyl)phosphonium chloride (THPC) as reducing agent and utilized to prepare Ag, Pt, and Pd nanoshells, as well as hybrid Pt/Ag nanoshells, on silica cores. 出版日期： 2016-01-01 出處： RSC advances, 2016-01, Vol.6 (72), p.6815-68159 資源來源： Royal Society of Chemistry 識別號： ISSN: 2046-2069 識別號： EISSN: 2046-2069 識別號： DOI: 10.1039/c6ra10717f
