What is copper oxide?

Copper oxide (chemical formula: CuO) is a black solid copper oxide. This is a strong electrolyte. It is insoluble in water and ethanol, soluble in acid, ammonium chloride and potassium cyanide solution, and slowly soluble in ammonia solution.

Preparation of copper oxide

Laboratory preparation method: CuSO4 and other copper salts react with alkali (NaOH) to generate Cu(OH)2, and Cu(OH)2 is heated to decompose to obtain copper oxide, and copper metal in the air can also be obtained by heating, or hydrogenated by heating Copper, copper nitrate, basic copper carbonate method. Industrial processes include copper powder oxidation, copper nitrate thermal decomposition, copper carbonate thermal decomposition, copper wire or copper powder nitrification, and conductivity water dissolution.

Overview of copper oxide CuO powder

Copper oxide is an inorganic substance with a chemical formula of CuO. It is a black oxide of copper, slightly amphiphilic and slightly hygroscopic. Copper oxide is almost insoluble in water or alcohol. Copper oxide dissolves slowly in ammonia solution, but quickly dissolves in ammonium carbonate solution; it dissolves in alkali metal cyanide and strong acid solution; hot formic acid and boiling acetic acid solution easily dissolve oxides. Copper oxides are mainly used in the manufacture of rayon, ceramics, glazes and enamels, batteries, petroleum desulfurizers, pesticides, hydrogen production, catalysts and green glass

Application of copper oxide CuO powder

Copper oxide is an important p-type semiconductor material with a narrow band gap (1.2-1.5 eV) because it has good thermal and photochemical stability, high temperature superconductivity and high electrochemical activity. The copper oxide method has been widely used in the fields of catalysis, sensing materials, superconducting materials, thermoelectric materials, glass, ceramics, lithium ion batteries and even medicine.

Copper oxide is used as a catalyst. It is a metal oxide that can be used as a hydrogen peroxide catalyst, but manganese dioxide is more active than copper oxide.

In a chemical reaction, the chemical reaction rate of the reactants can be changed (increase or decrease) without changing the chemical balance, and the substance whose quality and chemical properties have not changed before and after the chemical reaction is called a catalyst (solid catalysts are also called catalysts. According to statistics, More than 90% of industrial processes use catalysts, such as chemical, petrochemical, biochemical and environmental protection.

1. It can be used as organic synthesis catalyst, analytical reagent (for nitrogen determination), oxidant, catalyst and petroleum desulfurization. It can also be used to determine carbon in organic compounds.

2. Used as a colorant in the glass, enamel and ceramic industries, as an anti-Zou agent in coatings, and as a polishing agent in optical glass. Used in the manufacture of dyes, organic catalyst carriers and copper compounds. Used in rayon manufacturing industry as a desulfurizing agent for grease. Used as a raw material for the manufacture of other copper salts, as well as a raw material for the manufacture of artificial gems.
