Gas sensor and member using composite of metal oxide material semiconductor nano structure and graphene, and manufacturing method thereof

摘要

The present invention relates to a member for a gas sensor, a gas sensor using the same, and a method of manufacturing the same. Specifically, the present invention relates to a member for a gas sensor using a complex of a metal-oxide semiconductor nanostructure formed using an optical sintering process and graphene, a gas sensor, and a method of manufacturing the same. The present invention relates to a member for a gas sensor using a metal-oxide semiconductor nanostructure and graphene which includes multiple nanoparticles formed of a metal-oxide semiconductor; a one-dimensional or multi-dimensional nanostructure formed of the nanoparticles; and a graphene catalyst bound to a surface of the nanostructure, wherein the graphene catalyst has a form wherein graphene material of a two-dimensional flat or curved structure is crushed, thereby having a high sensitivity characteristic capable of detecting the infinitesimal amount of gas by a simple detection process, having excellent selectivity to detect various gases, maximizing a catalytic function of the graphene material used as a catalyst, and being produced through an efficient process.
