Surfactant-free synthesis of metal and metal oxide nanomaterials: a perspective

Abstract

Metal and metal oxide nanomaterials have attracted much interest in medical, pharmaceutical, biological, biomedical, and catalytic applications due to their high surface-to-volume ratio and fascinating physicochemical properties. To date, a...

Iron oxide-promoted photochemical oxygen reduction to hydrogen peroxide (H2O2)

“…Here we report an improved preparation method compared to the original synthesis of Fe 3 O 4 NPs regarding solvent, energy consumption, workup and overall sustainability, 93,94 and provide a scope of different nanoparticles, which can be synthesized and purified via a sustainable and facile route within six hours (Fig. 1A and B).…”

Laser-based synthesis of silver nanoparticles embedded in cellulose paper for catalytic reduction of azo dyes and SERS sensing of pesticides

“…Unlike chemical synthesis techniques, the PLAL technique can be employed to produce surfactant-free metallic nanoparticles that have a larger surface area than surfactant-coated nanoparticles, increasing their reactivity. Metallic nanoparticle fabrication without using toxic metal precursors and chemical-reducing agents is currently a priority area of research [33][34][35]. Previously, several studies have utilized pulsed laser ablation in liquid technique for synthesizing colloidal Ag NPs.…”

Surfactant-free synthesis of Ag@TiO2 and CuO@TiO2 photocatalyst: a comparative study of their photocatalytic activity for reduction of nitroaromatics in water

“…However, the presence of these substances might block the active site of the catalyst surface and could negatively affect the catalytic and electrochemical properties of the synthesized nanoparticles. So, these additives, surfactants etc need to be removed from the catalyst surface which involves energy and time intensive steps adding the risk of structural change of the synthesized catalyst [23,24]. To overcome this problem, various dopants, including both metals and non-metals, could be incorporated over the surface of TiO 2 [25,26].…”
