Single-step synthesis of gold-silver alloy nanoparticles in ionic liquids by a sputter deposition technique.
نویسندگان
چکیده
The simultaneous sputter deposition of gold and silver onto ionic liquids formed bimetallic alloy nanoparticles, which exhibited composition-sensitive surface plasmon resonance, the peak wavelength being red-shifted with an increase in the surface area of the gold foil targets sputtered.

Single-step preparation of two-dimensionally organized gold particles via ionic liquid/metal sputter deposition.
Sputtering of noble metals, such as Au, Ag, Pd, and Pt, onto room-temperature ionic liquids (RTILs) enabled the formation of monoparticle films composed of spherical noble metal nanoparticles on the liquid surface only when the RTILs used contained hydroxyl-functionalized cations as a component. Sputter deposition of these metals under the same conditions simply produced well-dispersed metal pa...
متن کاملLocal Structure of Au Nanoparticles in Ionic Liquids
Introduction Sputter deposition technique provides extremely clean method to synthesize Au nanoparticles in ionic liquids without any stabilizing agents [1]. We have investigated the control factor for the size of Au nanoparticles prepared by this method. In this method, the length of alkyl chain of cation and the temperature of ionic liquids have a big role [2-4]. Especially, the temperature i...
متن کاملComposition-dependent electrocatalytic activity of AuPd alloy nanoparticles prepared via simultaneous sputter deposition into an ionic liquid.
Homogeneously alloyed bimetallic particles of AuPd with an average size of ca. 2 nm were successfully prepared by simultaneous sputter deposition of Au and Pd in an ionic liquid in the absence of any additional stabilizing agents. The chemical composition of the AuPd alloy was tunable depending on the area fraction of Au plates in the Au-Pd binary targets for sputtering. The particles were immo...

Materials and Methods: Firstly, Ag-Au alloy NPs with Au/Ag molar ratio of 1:1 was f...
متن کاملIonic liquids for synthesis of nanoparticles (A review)
An ionic liquid (IL) is a salt in the liquid state. In some contexts, the term has been restricted to salts whose melting point is below some arbitrary temperature, such as 100 °C. While ordinary liquids such as water and gasoline are predominantly made of electrically neutral molecules, ionic liquids are largely made of ions and short-lived ion pairs. These substances are variously called liqu...
