摘要: Abstract Stable Nickel nanoparticles have been synthesized by a novel synthetic route based on the reduction of NiCl 2 ionic clusters in confined space reversed micelles. The reaction was carried out adding anhydrous NaBH 4 /ethanol solution to nanoencapsulated bis(2-ethylhexyl)sulfosuccinate (AOT) micelles presence n -dodecylmercaptane as capping agent. As highlighted FT-IR, an extraction with water eliminates surfactant and side products leaving lipophilic be dispersed organic solvent. UV–Vis investigation ascertained formation stable metal exhibiting optical properties.
