- CO2 sensor comprising CuO-SnO2 nanocomposite fiber and the method for manufacturing thereof

摘要

The present invention relates to a carbon dioxide sensor and a method of manufacturing the same, and more particularly, to a carbon dioxide sensor including a copper oxide-tin oxide composite nanofiber and a method of manufacturing a mixed solution by mixing a polymer, tin and a copper precursor with a solvent, ); Electrospinning the mixed solution of step 1 to form nanofibers on the substrate (step 2); And a step (3) of heat treating the nanofibers formed on the substrate in the step (2). The present invention also provides a method of manufacturing a carbon dioxide sensor comprising the copper oxide-tin oxide composite nanofiber. The carbon dioxide sensor made of electropositive copper oxide-tin oxide nanofiber according to the present invention is characterized in that since tin oxide and copper oxide form a pn junction and are arranged at a fixed Fermi level and energy band, they can exhibit excellent electron conductivity at the interface, 1 ppm of carbon dioxide can be detected.
