Gas Sensing Based on Carbon Nanostructures

Raz Jelinek, ben gurion university, beer sheva, israel (

Development of broad-based, readily-implemented, sensitive, and selective gas and volatile organic compounds (VOCs) sensors is a significant challenge in environmental monitoring.  We describe new types of gas sensors comprising innovative carbon nanomaterials, specifically nano-porous graphene oxide (pGO) and carbon-dots.  In both cases we designed composite systems providing significant accessible surface area for adsorption of gas molecules.  In particular, we show that excellent sensitivity, selectivity, and dynamic range can be accomplished.
