Synthesis Nanoparticles of Copper and Dicopper Oxide via Change Atmosphere of Copper Ablation

Abstract

The fabrication technique to synthesis dicopper oxide nanoparticles (Cu2ONPs) and copper nanoparticles (CuNPs) is laser ablation by a pure copper rod. To save the environmental system, we converted setup of device to develop the clean technology. In addition, the solvent using in both systems is water (green chemistry) without agent or surfactant. The average size of Cu2ONPs is 20 nm via enclosed platform of air under 600 mJ of laser power for 1h. However, the average size is 12 nm to generate CuNPs under N2 gas and 600 mJ of laser power for 1h. The morphology and the shape of the particles explain by Scanning Electron Microscope (SEM) images and Transmission Electron Microscopy (TEM) images. Also, the average size of the nanoparticles proved by measuring of 100 particles by using TEM image. In addition, The High-Resolution Transmission Electron Microscopy (HRTEM) image explains the distance between the layers in CuNPs which is 0.21 nm. The X-ray diffraction (XRD) and Attenuated Total Reflection-Fourier Transform Infrared (ATR-FTIR) of the product show the type of nanoparticles’ structure.
