Abstract

Copper nanoparticles (CuNPs) were prepared with different diameters by sonoelectrodeposition technique using Electrodeposition process coupled with high-power ultrasound horn (Sonoelectrodeposition). The particle diameter of the CuNPs was adjusted by varying CuSO4 solution acidity (pH) and current density. The morphology and structure of the CuNPs were examined by X-ray diffraction (XRD) and Scanning Electron Microscopy (SEM). It was found that the size of the produced copper nanoparticles ranged between 22 to 77 nm, where the diameter of CuNPs increases with reduction the solution acidity from 0.5 to 1.5 pH and increasing the current density of the deposition from 100 to 400 nm. Finally the produced CuNPs were pressed to fabricate disc filter and then the permeability, porosity, and filtration efficiency were determined which showed good efficiency.

Highlights

Metal nanoparticles have attracted much attention in nanoscale science and engineering technology over the past decade due to their unusual chemical and physical properties, such as catalytic activity, and novel electronic, optical and magnetic properties [1]
The crystallinety of the produced CuNPs at all pH values were examined by X-ray diffraction (XRD), as shown in Fig. 2, these spectra revealed a nanosized crystallites partially oxidized copper nanoparticles at all (0.5, 1 and 1.5) pH values using 100 mA/cm2 current density
The order of the variation of the crystallite size are somehow different from the results estimated using Scanning Electron Microscopy (SEM) techniques, this may attributed to the fact that the crystallite size deduced using Scherrer equation is totally different from particle size or grain size, so this results will not useful to confirm the effect of acidity on the particle size

Summary

Introduction

Metal nanoparticles have attracted much attention in nanoscale science and engineering technology over the past decade due to their unusual chemical and physical properties, such as catalytic activity, and novel electronic, optical and magnetic properties [1]. Iraqi Journal of Physics, 2018 include catalysts, absorbents, chemical and biological sensors, optoelectronics, information storage, and photonic and electronic devices [2] Various methods, such as wet chemical reduction, reverse micelles, and electrochemical and sonoelectrochemical deposition techniques [3]. Sonoelectrodeposition method is a simple environmental friendly and cost effectiveness method used to produce metallic nanosized materials compared to most of other methods including radiation, thermal decomposition, and vapor deposition, reduction in microemulsions and chemical reduction [7]
