Abstract

A simple, facile electrochemical route to fabricate morphologically different copper oxide nanoparticles (CuO NPs) using different solvents has been developed by keeping other parameters constant such as current (100mA), electrolyte (sodium hydroxide), time (2 hrs), while solvent has been varied (pure water or water-methanol or water-acetonitrile). The electrolysis has been carried out at sacrificial copper anode and inert platinum cathode in undivided cell under amperostatic condition at room temperature. CuO NPs isolated after electrolysis and calcinations at 900°C have been systematically characterized by FTIR, XRD, SEM and TEM. SEM micrograph revealed the morphologies such as snow white particles, spherical potato shape particle and cluster of spherical ball shape bee hive have been obtained when water, water-methanol and water-acetonitrile (water-ACN) respectively has been used as solvent. TEM micrograph revealed that average grain size varying from 2-36 nm was obtained in presence of water-acetonitrile solvent. As compared with water or water-methanol mix solvent the size of CuO NPs with smaller size has been obtained from water-acetonitrile mix solvent.
