Nano Copper Oxide (CUO) introduction:
Nano Copper oxide appear as a brownish-black powder. They can be reduced to metallic copper when exposed to hydrogen or carbon monoxide under high temperature. Insoluble in water. dissolve slowly in alcohol or ammonia solution. Soluble in dilute acids, NH4Cl, (NH4) 2CO3, potassium cyanide solution. They are graded harmful to the environment with adverse effect on aquatic life.

Nano Copper Oxide Manufacturing Process:
Nano Copper oxide powder can be synthesized using the aqueous precipitation method. In this method, copper acetate is used as a precursor and sodium hydroxide as a stabilizing agent.
Nano Copper Oxide Application:
Nano copper oxide is a widely used material. It has been applied to the catalyst, superconducting materials, thermoelectric materials, sensing materials, glass, ceramics and other fields.
As burning rate catalyst in rocket propellant. It can greatly improve the homogeneous propellant burning rate, lower pressure index, and also perform better as a catalyst for the AP composite propellant Can be applied to the catalyst, superconducting materials, thermoelectric materials, sensing materials, glass, ceramics and other fields.
As gas sensors, Since 1931, Braver, and others found that copper oxide is sensitive to moisture comparison, copper oxide in sensor has become an important object of study.Nano copper oxide has high specific surface area, highly active, foreign bodies and extremely small and other advantages of the external environment such as temperature, light, moisture, etc, can greatly improve the sensor's corresponding speed, sensitivity and selectivity.Frietsch etc. The nanometer copper oxide coated on the surface of other materials.Surface of the results of the study, the sensor cover 5-30 nanometer copper oxide film can greatly improve the sensor to the selectivity of CO and ethanol gas, provide advanced means for testing environment quality.
