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 is a widely used material. It has been 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.
