Copper(I) Oxide Nanoparticles

Copper(I) oxide, with the chemical formula Cu₂O, is a monovalent copper oxide that appears as a bright red powdery solid. It is almost insoluble in water and disproportionates into divalent copper and elemental copper in acidic solutions. In moist air, it gradually oxidizes to black copper(II) oxide. It has a density of6.0 g/mL, a melting point of1235°C, a boiling point of1800°C, a refractive index of2.705, and a flash point of1800°C.

Solubility: Insoluble in water and alcohol; soluble in hydrochloric acid, ammonium chloride, and ammonia water; slightly soluble in nitric acid. Dissolves in hydrochloric acid to form white copper(I) chloride crystalline powder. Reacts with dilute sulfuric acid and dilute nitric acid to form copper salts. Turns blue rapidly in air. Soluble in concentrated alkali, ferric chloride, and other solutions.

Cu₂O is ap-type semiconductor with a bandgap of2.1 eV, exhibiting unique optical, electrical, and photoelectrochemical properties. It also possesses strong adsorption capabilities, low-temperature paramagnetism, and other characteristics. As a photocatalyst, its greatest advantage is its ability to absorb visible light from sunlight, generating photogenerated electron-hole pairs that effectively catalyze the degradation of industrial dye wastewater and nitrogen-containing pesticides. This largely compensates for the shortcomings of semiconductors with larger bandgaps, such asTiO₂, which struggle to catalyze degradation within the visible light wavelength range. It shows great potential in the field of photocatalytic degradation of organic pollutants. The feasibility of using nanomaterials for photocatalytic degradation of organic compounds in wastewater has been widely confirmed.
