Carbon nanomaterials for room temperature gas sensing

Piloto, Carlo (2016) Carbon nanomaterials for room temperature gas sensing. PhD thesis, Queensland University of Technology.



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.

Impact and interest:

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.

Citations counts from the Google Scholar™ indexing service can be viewed at the linked Google Scholar™ search.
