Synthesis of Copper (II) Oxide (CuO) Nanoparticles and Its Application as Gas Sensor

Copper sulfate was used as a precursor to prepare CuO nanoparticles in reverse micelles (o/w microemulsion). This is a technique which allows the preparation ofultrafine metal oxide nanoparticles within the size ranging from 50 to 60 nm. The preparation of copper (II) oxide nano particles was investigated in the inverse microemulsionsystem. Therefore, the nucleation of metal particles proceeds in the water capsules of the microemulsion. Tween 80 was added as surfactant. The productswere characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The study provides a simple and efficient route to synthesize CuO nanoparticles at room temperature.
