Copper(I) oxide - Wikipedia

Copper(I) oxide may be produced by several methods. Most straightforwardly, it arises via the oxidation of copper metal: 4 Cu + O2 → 2 Cu2OAdditives such as water and acids affect the rate of this process as well as the further oxidation to copper(II) oxides. It is also produced commercially by reduction of copper(II) solutions with sulfur dioxide

Copper nanoparticle - Wikipedia

Various methods have been described to chemically synthesize copper nanoparticles. An older method involves the reduction of copper hydrazine carboxylate in an aqueous solution using reflux or by heating through ultrasound under an inert argon atmosphere. This results in a combination of copper oxide and pure copper nanoparticle clusters, depending on the method used.
