Metal and Metal Oxide synthesis by Electrical Explosion of Wire

Metal nanoparticles (MNPs) and metal oxide (MONPs) nanoparticles were selectively produced in large quantities by the Electrical Explosion of Wire (EEW) process in different conditions. Transmission Electron Microscopy (TEM), laser particle size analyzing, X-ray diffraction (XRD), and FT-IR spectroscopy were carried out to characterize the purity, morphology, particle and crystallite size of the nanoparticles. The effects of conditional parameters on the particle size were analyzed. The results show that the wire diameter, feed rate, pulse time, voltage, and electrode distance are the main five factors. An ultimate Response Surface Methodology (RSM) design showed the particle size increases with decreasing voltage and increasing other factors
