Graphene catalyst-decorated metal oxide nanorod, method for fabricating the same and sensors comprising the same

摘要

The present invention relates to a sensor which prevents the modulation of resistance change characteristics of metal oxide nanorod on gas by combining minute graphene or graphene fine aggregates on the surface of the metal oxide nanorod. The present invention provides improved sensitivity characteristics, rapid response rates and recovery rates, selectivity, and low drive characteristics by adopting metal oxide nanorod combined with graphene or graphene aggregate to the gas sensor.
