Highly sensitive ethanol vapor sensor based on reduced graphene oxide

Original language description

Carbon allotrope forms, especially graphene or nanocrystalline diamond have become the subject of current research due to their remarkable electrical, thermal, mechanical and chemical properties. Here, their particular use as gas sensors becomes attractive in the sense of technological simplicity and flexibility in various detection principles (chemiresistor, FET and electrochemical). Moreover, they benefit from a large surface area, good electrical conductivity, simple synthesis and tunable surface functionalization. In the current work, we investigate and compare the responses of different gas sensing layers (graphene oxide, reduced graphene oxide and nanocrystalline diamond) to three different ethanol vapor concentrations (20, 50 and 100 ppm) at room temperature and relative humidity of 40 % with nitrogen as the carrier gas. Moreover, the nanocrystalline diamond sensing layers were functionalized by hydrogen and oxygen, and graphene oxide was thiolated.
