Abstract: Disclosed are a member for a gas sensor, a gas sensor using the member, and a method of fabricating the same. Specifically, disclosed are a member for a gas sensor using a metal oxide nanofiber material in which nanocatalysts have been uniformly bound and functionalized using chitosans with which nanoparticle catalysts have been combined, a gas sensor using the member, and a method of fabricating the same.

Abstract: Disclosed are polymer nanofiber sensors for detecting gas, which generates visible color change although a specific gas having a concentration of less than 1 ppm is exposed to the sensor in a short time, in which it is impossible to detect the gas using existing colorimetric sensors, through securing high surface area and porosity, and a method of the same.
