Abstract:
A member for a metal oxide nanofiber based gas sensor can include a metal nanoparticle catalyst and can be formed to be functionalized by binding the metal nanoparticle catalyst and an alkali or alkaline earth metal through electrospinning and heat treatment processes. The member can detect a trace amount of a gas with high selectivity and ultra-high sensitivity by uniformly binding the alkali or alkaline earth metal and the metal nanoparticle catalyst through electrospinning and high-temperature heat treatment.
