Sonochemical synthesis of amorphous Cu and nanocrystalline Cu2O embedded in a polyaniline matrix

Tunable Cu2O Nanocrystals Fabricated by Free Dealloying of Amorphous Ribbons

“…Therefore, Cu 2 O particles with different sizes and morphologies are highly desirable for these applications. So far, Cu 2 O has been prepared by several different methods [13][14][15][16], such as sonochemical methods [11], solvothermal [17], and hydrothermal methods [18]. In this paper, we present a new approach to design tunable-structured Cu 2 O nanocrystals by free dealloying Cu-based metallic glasses in hydrofluoric acid (HF) or HCl aqueous solutions and investigate the morphology evolution of Cu 2 O particles with different conditions.…”

“…Cu 2 O, which is an important p-type semiconductor with a direct band gap of 2.17 eV [7], has been widely studied as a promising material for applications in gas sensors [8], in solar energy conversion [9], as an electrode in lithium ion batteries [10], as a photocatalyst for the degradation of organic pollutants [11] and for the decomposition of water into H 2 and O 2 under visible light irradiation [12]. Therefore, Cu 2 O particles with different sizes and morphologies are highly desirable for these applications.…”

A green method for the synthesis of Copper Nanoparticles using L-ascorbic acid

“…Pulsed laser ablation [4], vacuum vapor deposition [5], pulsed wire discharge [6] and mechanical milling [7] are physical techniques while Chemical reduction [8], Microemulsion techniques [9], sonochemical reduction [10], Electrochemical [11], Microwave assisted [12], and hydrothermal [13] are chemical approaches for the synthesis of nanoparticles. Biological or biosynthesis [14] techniques are also considered as chemical methods.…”

Current view on biomedical applications of synthetic metal-polymer nanocomposites

“…The physical and thermal properties of the as prepared composite materials were presented and mechanisms for the formation of these products were discussed. They are in opinion that this technique can also be applied to the preparation of different metals or metal oxides embedded in polyaniline matrices [12]. Gangopadhyay and De (2000) have been discussed in detail on the nanocomposites, throwing light on their synthesis techniques, properties and applications [13].…”
