Project Description
Gas sensors play a significant role in numerous application fields such as environmental monitoring, industrial production and safety, medical diagnosis, military and aerospace. The most important parameter that determines the sensitivity of gas sensors is their specific surface-to-volume ratio. A larger detecting surface of the nanostructured materials leads to greater adsorption of gas species on them and thus increased sensing capability. Graphene is a one-atom thick carbon nanomaterial. Due to the infinitesimal thickness of graphene sheets, they are essentially 'all surface' making graphene and ideal material for gas sensing. However, the chemical stability of graphene means that it has little selectivity for gas sensing. Traditional chemresistive gas sensor are made from metal oxides to catalytically interact with analytes facilitating their selectivity.
In this project we explore the use of catalytic transition metal oxide nanoparticles to develop selectivity in graphene gas sensors.
