What is Copper(I) Oxide

Copper(I) oxide is a chemical compound containing copper and oxygen. In this oxide with the empirical formula Cu2O, copper is monovalent. Copper(I) oxide is a reddish-brown solid and turns black when heated, but returns to its original color upon cooling.

Copper(I) oxide is a yellow to red powder, depending on the particle size, and is practically insoluble in water. On the other hand, it is soluble in dilute acids. Copper (I) oxide is soluble in ammonia or ammonia water and forms a complex. The formed [Cu(NH3) 2] + complex, unlike the [Cu(H2O) 4] + complex, is stable. The latter is disproportionate in Cu and [Cu(H2O)6]2+.

Moist copper(I) oxide is easily oxidized to blue copper(II) hydroxide in air. In contrast, dry copper(I) oxide does not react.

What is Copper Oxide used for?

Copper(I) oxide is used for antifouling paints, for example for underwater painting. The dissolving copper is toxic to algae and inhibits its buildup on the ship's sides. In addition, copper (I) oxide is used as a starting material for the production of various copper compounds. It is also used as a pigment for coloring glass and enamel red, for producing gold flux, as a fungicide and as a catalyst.

Copper(I)oxide is also a semiconductor with a direct bandgap of about 2 eV and was used in the construction of rectifier diodes in the 1920s. Such copper oxide rectifiers consisted of copper discs coated with Cu2O. Selenium and later germanium and silicon later supplanted Cu2O as a semiconductor material, but basic studies are still being done on Cu2O because electrons in this material can be excited very easily.

In November 2019, the University of Waterloo (Canada) presented a process in which copper (I) oxide serves as a catalyst for the "artificial leaf". Carbon dioxide (CO2) is introduced into a mixture of water and copper(I) oxide. When exposed to visible light, a chemical reaction takes place in which CO2 reacts to form oxygen and methane. This process allows renewable methane to be economically produced as an alternative to fossil fuel.
