The present invention relates to a member for a gas sensor, a gas sensor using the same, and a method of manufacturing the same and, specifically, to a member for a gas sensor using a catalyst-metal oxide nanofiber composite material, a gas sensor, and a method of manufacturing the same capable of removing by pyrolyzing a polymer sacrificial layer template coated with a catalyst; forming a pore in the surface and the inside of a metal oxide nanofiber having a one-dimensional structure using a feature that a catalyst is transferred and functionalized for a metal oxide semiconductor nano-fiber; and selectively binding a catalyst in a position where a pore is formed. According to the present invention, as a surface of a polymer sacrificial layer template which can be removed through heat treatment at high temperatures is coated with a catalyst, after a composite nanofiber is formed by mixing the polymer sacrificial layer template coated with a catalyst with an electrospinning solution and electrospinning the same, the sacrificial layer template is removed through high temperature heat treatment, thereby configuring a member for a gas sensor using a metal oxide nanofiber having a one-dimensional structure capable of forming pores having different sizes and selectively binding a catalyst in the pore formed positions at the same time. Therefore, provided are the member for a gas sensor which can be mass-manufactured by a processing method capable of maximizing a catalyst effect using a catalyst to be selectively bound by having excellent selectivity to detect various gases with high sensitivity characteristics of detecting a small amount of gases through a simple detecting process, and efficiently forming a pore and binding a catalyst to the same at the same time; the gas sensor; and the method of manufacturing the same. |
