Preparation of Cu Nanoparticles with a chemical reduction method

Moghadaseh Fallahzadeh, Maryam Reisie and Hossein Eisazadeh

Abstract: In this research, Cu nanoparticles were prepared by chemical reduction mthod with Na2HPO4 and CuSO4 in aqueous media using PVP and PVA as surfactant. Particle size and concentration of Cu nanoparticles were investigated by using scanning electron micrograph and energy dispersive X-ray microanalysis. The Results indicate that particle size and homogeneity of nanoparticles were dependent on the type and concentration of surfactant. Also, it was found that the range of particle size was between 7 - 58 nm. The surface analysis of the obtained product was determined by energy dispersive X-ray microanalysis (EDX), which has provided valuable information regarding the component’s concentration of product, results were shown with one step filtration of solution, it was achieved 80 percent concentration of cu nanoparticle. In one case, SEM image reveals nanostructure of Cu particles with a cauliflower-like morphology. An individual cauliflower consists of several branches of width less than 100 nm and a length of few micrometers
