Abstract
For the preparation of copper nanoparticles several methods, i.e., thermal reduction, mechanical attrition, chemical reduction metal vapour synthesis, radiation methods, laser ablation and micro emulsion techniques were developed in the past. Electrolytic deposition is one of the most suitable, simplest and low cost methods which are used for wide range of materials. In the present investigations, efforts were put to produce copper nano powder using electrolytic technique. It could be possible to obtain near nano copper powder of 258 nm size using high cathode current density of 1100 A/m2 in sulphate bath. The specific surface area and shape of the particles were found to be 23.2 m2/g and irregular, respectively.
Highlights
The field of nanoscience and nanotechnology has recently become one of the most important areas of knowledge encompassing various scientific disciplines, including physics, chemistry, biology and engineering
Size distribution and specific surface area of the powder produced was studied by laser technique using Malvern Mastersizer 2000, while the morphology was studied using ZEISS Supra-50 FESEM
The particle size obtained in this case was significantly smaller (5.2 μm) than the particle size obtained at low current density, and a marginal increase in specific surface area
Summary
The field of nanoscience and nanotechnology has recently become one of the most important areas of knowledge encompassing various scientific disciplines, including physics, chemistry, biology and engineering. Interest in this discipline is mainly due to two reasons. One dimensional nanomaterial (tubes, wires, rods, etc.) is an important class of nanostructured materials with potential applications in electronics, composite fabrications or sensor developments [1]. (2014) Preparation and Characterization of Near Nano Copper Powder by Electrolytic Route. Copper nanoparticles synthesized by mechanical chemical method have low purity and wide particle size distribution. In the present investigations, it was planned to produce nano copper powder by using electrolytic deposition from copper sulphate bath under suitable bath conditions [5] and additives like boric acid and glycerine [6]
