“…Kan et al reported a composite nano-structure of a core of Au and a shell of Ag with PVP which were prepared under ultrasound using Ag(NH 3 ) 2 -(OH) and HAuCl 4 as precursors. 55 Anandan et al reported bimetallic Au-Ag with a core-shell structure was generated sonochemically at 20 kHz in room temperature and Ar atmosphere. 56 Besides, Martínez-Casillas and Solorza-Feria synthesized Pd/Cu bimetal with regular spherical agglomerates using ultrasound, which had an average size of 8 nm.…”

“…Usually, the reduction order of metals ions is controlled by their redox potential. It is well known that the standard reduction potential of (AuCl 4 – )/Au pair (0.99 V vs standard hydrogen electrode, SHE) is higher than that of the Ag + /Ag pair (0.80 V vs SHE) . Thus, when loaded Au 3+ and Ag + ions within PVA films were exposed to irradiation, two critical reactions have to be considered simultaneously.…”

Summary Gold nanoparticles were in situ synthesized via irradiation process, using PVA, (PVA:Cs), and (PVA:PAM) as host polymeric matrices. The effect of irradiation dose, polymer content, polymer combination AgNO3, chitosan, and poly acrylamide were studied. Gold nanoparticles (AuNPs) have spherical nanoparticles shape with different size ranging from 10−35 nm, which were characterized by ultraviolet‐visible (UV‐VIS) spectroscopy, X‐ray spectroscopy and transmission electron microscopy. Fourier transform infrared spectroscopy (FTIR) shows the spectral shift together with reduced intensity of the −OH stretching vibration upon incorporation of the Au nanoparticles indicating the coordination between Au nanoparticles and the OH groups originating from the PVA chains. The synthesized gold nanoparticles have been successfully applied as a catalyst in the degradation of methyl orange and methylene blue by NaBH4.

“…Core-shell nanostructures consisting of Au-NPs within shells of Ag NPs-filled polymer (Aucore/Ag-PVP-shell) were synthesized by Kan and co-workers in a two-step sonication-assisted reduction procedure [106]. Ag-NPs acted as reductive agent for Au(III) ions in the presence of poly(vinylpyrrolidone) (PVP).…”

Merging Metallic Catalysts and Sonication: A Periodic Table Overview

Abstract:This account summarizes and discusses recent examples in which the combination of ultrasonic waves and metal-based reagents, including metal nanoparticles, has proven to be a useful choice in synthetic planning. Not only does sonication often enhance the activity of the metal catalyst/reagent, but it also greatly enhances the synthetic transformation that can be conducted under milder conditions relative to conventional protocols. For the sake of clarity, we have adopted a structure according to the periodic-table elements or families, distinguishing between bulk metal reagents and nanoparticles, as well as the supported variations, thus illustrating the characteristics of the method under consideration in target synthesis. The coverage focuses essentially on the last decade, although the discussion also strikes a comparative balance between the more recent advancements and past literature.
