Rapid Green Synthetic Protocol for Novel Trimetallic Nanoparticles

Metallic nanocomposites and nanotubes can be rapidly prepared under microwave irradiation (MW) from an aqueous solution of metallic precursors in the presence of trisodium citrate as a reductant. For the nanotubes nanoparticles are stabilized by poly(N-vinyl-2-pyrrolidone) (PVP), a protecting agent. PVP is a typical capping and structure-directing agent used for the synthesis of various metallic nanostructures. In this work, we have demonstrated for the first time an MW irradiation approach for the synthesis of trimetallic nanocomposites and nanotubes. The resulting nanohybrids were characterized by UV-Vis spectroscopic analysis, high-resolution scanning electron microscopy (HR-SEM), energy dispersive X-ray spectroscopic analysis (EDX), and X-ray diffractometer (XRD) techniques.
