| 中文摘要 | A simple and facile method was developed to fabricate alloyed Pt-Ag nanoislands on Au nanorods (denoted as Au@Pt-Ag NRs). The island growth mode of Pt on the Au rod was employed to guide the growth behavior of Pt-Ag alloys. The formation of the Pt-Ag alloy was confirmed by scanning electron microscopy (SEM). transmission electron microscopy (TEM), XRD (X-ray diffraction), XPS (X-ray photoelectron spectroscopy), UV-visible absorption spectra, and electrochemical characterization. The alloy compositions can be tuned. The within the broad miscibility gap from Ag(9)Pt(91) to Ag(83)Pt(17) by controlling the ratios of PtCl(4)(2-)/Ag(+). The Au@Pt-Ag NRs show tunable surface plasmon resonance (SPR) and enhanced catalytic activity for methanol electro-oxidation, pointing to a potential future of nanometerized Pt-Ag alloys in fuel cells and other related fields. Apart from Pt-Ag. this strategy may be applied to the formation of Pt-related bimetallic (trimetallic) systems. |
