Copper oxide (formula: CuO) is a black copper oxide, slightly bisexual, slightly hygroscopic. Relative molecular mass of 79.545 and density of 6.3 ~ 6.9 g / cm3, melting point 1326 ℃. Stable, non-toxic non-flammable, no special combustion and explosion characteristics.
Copper oxide nanorods has a surface effect, quantum size effect, volume effect and macroscopic quantum tunneling effect and other characteristics. Compared with ordinary copper oxide, nanoscale gives copper oxide nanorods the nature of special electrical, optical and catalytic. Electrical properties of copper oxide nanorods make it to the external environment such as temperature, humidity, light and other conditions very sensitive, so a nanometer copper oxide particles coated sensor, can greatly improve the response speed of the sensor, sensitivity and selectivity. Nanometer copper oxide can also be used as a solid rocket propellant burning rate catalyst, not only can improve the burning rate of propellant , but also reduce the pressure exponent. In catalysis, nano-copper oxide can be a good photocatalytic degradation of organic dyes. Nanometer copper oxide can be used as a P-type semiconductor material, is also a good light-sensitive material, but also used in glass and ceramics coloring agents, exhaust gas purification materials, contact materials.
Copper oxide nano-infrared absorption peak showing a clear width, and a clear blue shift. With this blue shift appearance, can be designed controllable light-absorbing material, and showing a good prospect on microwave absorbing, radar absorbing, stealth aircraft coating, etc.
US scientists use optical properties of copper oxide nanorod, successfully making greenhouse gas carbon dioxide into liquid fuel methanol, while addressing global warming, also received endless renewable energy.
Japanese scientists found that copper oxide nanoparticles have negative thermal expansion phenomenon. Complexing the negative thermal expansion material with other useful materials, you can achieve to control the thermal expansion coefficient freely, so it is possible to produce ultra-precision instruments and electronic components which will not crack in extreme environments.
Copper oxide nanorods can also be used for superconductivity, thermal resistance, paint additives, antibacterial materials, magnetic materials and so on.
