Title
Green Synthesis of Metallic Nanoparticles and their Catalytic Activity in Degradation of Azo Dye.
Abstract: Microwave (MW) rapid heating has received considerable attention as a new promising method for one-pot synthesis of metallic nanostructures in solutions. In this concept advantageous application of this method has been demonstrated for the green preparation of Pd Ru Au-Pd and Ru-Pd nanoparticles. By combining several characterizations such as UV–vis spectroscopy TEM XRD and DLS the product was proved to possess size in the order of nanoscale. Due to large surface area to volume ratio of nanoparticles catalytic degradation of Congo red azo dye was studied using the synthesized particles. Most of the literature deals with photocatalysis but drawbacks such as low quantum yields and requirement of UV light hinder its widespread acceptance as a practical remediation technology. Thus the catalytic activity of prepared mono and bimetallic nanoparticles in reduction of azo dye in dark conditions was explored. In addition to this electrocatalytic oxidation reactions of fuel cells using synthesized nanoparticles and synthesis and characterization of raspberry type hybrids will also be discussed.Bio: Sakshi Goel has received M.Sc.
