ABSTRACT
A one-pot and single-step reduction process for producing copper nanoparticles will be described. This process can be carried out at room temperature and nanocrystalline size is achieved by using greener stabilizing agent starch with hydrazine hydrate as a reducing agent in ambient condition. TEM images show that the particles formed are of spherical morphology and strongly support size distribution. FTIR spectra show that there is thin layer of starch molecule on the surface of copper nanoparticles that stabilize and protect it from air oxidation for several days. The synthetic procedure is the typical example for green synthesis of Cu nanoparticles at room temperature.
