The preparation of nano copper (II) oxide studied was investigated in the inverse microemulsion system. Therefore the nucleation of metal particles proceeds in the water capsules of the microemulsion. Tween 80 was added as surfactant. The products were 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. https://www.biotechrep.ir/article_69202_abbe69ec001dde56c5c38a124c16e508.pdf
