FABRICATION METHOD OF SNO2 NANOTUBES FOR GAS SENSORS AND SNO2 NANOTUBES PRODUCED BY THE METHOD

摘要

The present invention relates to a method for manufacturing a tin oxide nanotube and a gas sensor using the same, and more particularly, coating anodized aluminum template with a surfactant containing an amine group; Filling the tin oxide nanoparticles having a carboxyl group into the anodized aluminum mold frame coated with the surfactant; Performing a peptide binding reaction between the tin oxide nanoparticles and a surfactant; Removing excess tin oxide nanoparticles not used for the peptide bond and sintering at high temperature; Coating an electrode material on the sintered anodized aluminum mold and then etching the Al ₂ O ₃ oxide layer and aluminum with an etchant to produce tin oxide nanotubes; It relates to a gas sensor maximized efficiency.
