Facile solution synthesis of Ag@Pt core–shell nanoparticles with dendritic Pt shells

Li, Cuiling, Yamauchi, Yusuke·2013·Physical Chemistry Chemical Physics

Abstract

Ag@Pt nanoparticles with various dendritic Pt shells were successfully synthesized by using nonionic surfactants at room temperature. Our recent study demonstrated that the addition of nonionic surfactant plays an important key role in the synthesis of dendritic Pt nanostructures (J. Am. Chem. Soc., 2010, 132, 13636). Here we extend this synthetic concept to prepare various Ag@Pt nanoarchitectures. The different nanostructured Pt shells on the Ag core were confirmed by ultraviolet-visible absorption spectroscopy and transmission electron microscopy. As a preliminary electrochemical application, the obtained Ag@Pt nanostructures were applied in the methanol oxidation reaction (MOR) in 0.5 M H(2)SO(4) solution containing 0.5 M methanol. The Ag@Pt nanoparticles with thin dendritic Pt shells show superior CO-tolerance performance with a I(f)/I(b) value reaching 3.71. Our Ag@Pt nanostructures with good CO tolerant activity will be prominent catalysts for MOR.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
