PRODUCTION WITH PORTRAYAL OF NANOMATERIAL‘S: A STUDY

B. Swapna

Abstract :

 The paper focuses on the synthesis of Ni and NiCo nanoparticles and their application in the field of magnetism, catalysis & thin film. The characterization of the particles was conducted using TEM, XRD,FTlR,TGA–DSC,UV–vis spectroscopy, EDS. Ni and NiCo nanoparticles have been synthesized using two different mediums i.e aqueous and non aqueous respectively. Heterogeneous synthesis of monodisperse pure nickel nanoparticles in aqueous medium has been carried out using cetyltrimethylammonium omide and a lower alkylammonium omide mixture of tetraethylammonium omide and tetrabutylammonium omide. The presence of cetyltrimethylammonium omide alone results in the formation of a mixture of nickel hydroxide and nickel nanoparticles. The particles have been characterized using TEM, EDS, XRD, TGA—DSC and FTIR. The analysis showed that particles were spherical in shape, monodisperse, face centered– cubic with average size about 15 nm and were stable in air up to 325 0C. The nanoparticles have been used as a solid phase catalyst for the reduction of p–nitrophenol and methyl orange in the presence of hydrazine hydrate as reducing agent at different temperatures under varying conditions. The reduction process has been monitored by UV—vis analysis. The present study showed that nanoparticles were not poisoned after their repeated use. TEM analysis also confirms that nanoparticles were stable in the dispersed medium for longer times. The recapping of these nanoparticles has been done with TOPO
