Metal or metal oxide decorated two-dimensional material hybrids have been shown to exhibit excellent sensitivity performances if used as chemical gas sensors. We investigated the influence of operating temperature, relative humidity and UV irradiation of various metal oxide nanolayer decorated epitaxial graphene hybrid sensors during exposure to several gases of interest for air quality minoring. Furthermore, a data treatment method is introduced to further enhance sensor properties.
