What are copper and cuprous oxide?

Overview of Cuprous Oxide Cu2O powder

Cuprous oxide, chemical formula Cu2O, is a monovalent cupric oxide, bright red powder solid, almost insoluble in water, disproportionate into divalent copper and copper elements in an acidic solution, and gradually oxidized into black copper oxide in humid air.

 Cuprous oxide is commonly used as a pigment, biocide and antifouling agent in marine coatings. Rectifier diodes based on this material were used in industry as early as 1924, long before silicon became the standard. Copper(I) oxide is also responsible for the positive pink color of the Benedict test.

 What are copper and cuprous oxide Cu2O powder?

Copper is a reddish-orange metal with high thermal and electrical conductivity. It shares this ability with silver and gold because each of these elements has a "free agent" electron that can negotiate chemical bonds with any available atoms around it. All other electrons are tightly bound to their groups, but this electron is easily transferred.

 When copper is exposed to water molecules (two hydrogens and one oxygen), this free electron is transferred to an adjacent oxygen atom, combining it into a molecule. If only one copper atom is bound to an oxygen molecule, it is called copper oxide. If two copper atoms are combined with one oxygen atom, it is cuprous oxide. Cupric oxide is considered "fully oxidized", while cuprous oxide remains active.

The key to cuprous oxide is its active state, which makes it very effective as a fungicide. It is still producing reactive oxygen species, highly reactive molecules. These are unstable molecules that can cause damage to cellular structures.

 Application of cuprous oxide Cu2O powder

Cuprous oxide Cu2O nanoparticles are commonly used as pigments for marine pigments, fungicides and antifouling agents.

1. Suitable for pesticides.

2. Suitable for antibacterial fibers and clothing.

3. Cuprous oxide is also suitable for agricultural fungicides.

4. As a preservative, it is suitable for ship primer to prevent contamination and microorganisms.

5. For the manufacture of various copper salts and analytical reagents.

6. Used as a catalyst for organic synthesis.

Cuprous oxide is used to make antifouling paints on the bottom of ships (kills low-level marine animals). It is used as a fungicide, ceramic and enamel colorant, red glass colorant, and also used in the manufacture of various copper salts, analytical reagents and rectifier electroplating, crop fungicides and rectifier materials in the electrical industry. Cuprous oxide is also commonly used as a catalyst for the synthesis of organic compounds.
