A wide range of versatile fine inorganic materials, mainly used in printing and dyeing, glass, ceramics and catalysis and other fields. Nano copper oxide can be used as catalyst and catalyst carrier and electrode activation material, can also be used as rocket propellant, which as the main component of the catalyst, copper oxide powder in oxidation, hydrogenation, NO, CO, reduction and hydrocarbon combustion and other catalyst reactions have been widely used. Widely used in catalyst, superconducting materials, thermoelectric materials, sensing materials, glass, ceramics, lithium ion batteries and other fields. Used as glass, porcelain pigment, desulfurizer, catalyst, Also used in the rayon industry For the determination of carbon in organic compounds Used as analytical reagent, oxidant, catalyst and petroleum desulfurizer It is used as colorant for glass, enamel and ceramic industry, anti-zou agent for paint and polishing agent for optical glass. Used in the manufacture of dyes, organic catalyst carriers and copper compounds. It is also used in the rayon manufacturing industry and as a desulfurizer for oils and fats. It is used as a raw material for the manufacture of other copper salts, and is also a raw material for the manufacture of artificial gems. It can be used for determination of carbon in blue green pigment, artificial gemstone, gas analysis, colored glass, ceramic glaze, oil desulfurizer, organic synthesis catalyst. Nanometer copper oxide uses: (1) It is widely used as an important inorganic material in catalysis, superconductivity, ceramics and other fields. (2) Used as catalyst and catalyst carrier and electrode active material. (3) Used as colorant for glass and porcelain, optical glass polishing agent, catalyst for organic synthesis, oil desulfurizer, hydrogenating agent. (4) Manufacture of artificial gemstones and other copper oxides. (5) For the manufacture of rayon, as well as gas analysis and determination of organic compounds. (6) It can also be used as a burning rate catalyst for rocket propellant. Nano copper oxide powder has better catalytic activity and selectivity than large size copper oxide powder and others.
