Carbon nanomaterials for room temperature gas sensing

The aim of this research is to develop high performance gas sensors with low power consumption and high portability. This was achieved by synthesizing carbon nanomaterials decorated with alkali-metal dopants and metal oxides, and by optimizing ultrathin layer of carbon nanobutes coupled to a new deposition technique. These materials demonstrated excellent sensitivity at room temperature to both nitrogen dioxide and ammonia, down to ppm level, providing a new pathway to realise room temperature gas sensors. Our fabrication methods are highly scalable and do not involve the use of expensive equipment which makes them excellent candidates for mass production
