Abstract

Our objective in this paper is to study the effect of the current on the fabrication copper nanoparticles Cu-NPs and its effect on the yield and to investigate a new technique for plasma preparation of nanoparticles. A new instrument, which uses a three-phase current to support a double-arc discharge method for generating the plasma and evaporate the solids, is described. The crystal structure of nanoparticles, which was examined by X-ray diffraction XRD, shows that diffraction peaks for the Cu-NPs indicate that they are crystalline in nature. The morphology of the product was examined by Scanning Electron Microscope (SEM). From the micrograph, it was observed that the nanoparticles size ranges from 44 to123 nm. The particle size analyzer gives the size distributions with an overall sizing range. The particle size analyzer (PSA) constituents with SEM (the particles size ranges from 30-128 nm). The ultraviolet-visible (UV–Vis) spectrometry contributed to the analysis of size and optical properties of the nanoparticles through each current value (from 30A-110A). Fourier transform infrared (FTIR) spectroscopy analysis (4500 -500 cm−1) confirmed the presences of Cu-NPs by an appearance of no sharp peaks for any functional group. The developed technique was shown to be suitable for the preparation of Cu-NPs of different sizes. However, a scale-up of production rate often leads to an increase in particle size and broadening of size distribution. Copy Right, IJAR, 2018,. All rights reserved.
