Abstract

We report an ultrafast and sensitive hydrogen (H2) sensing platform using semiconducting single-walled carbon nanotubes (SWCNTs) decorated with tin oxide (SnO2) nanocrystals (NCs). The hybrid SnO2 NC–SWCNT platform shows a response time of 2–3 seconds to 1% H2 under room temperature and can fully recover within a few minutes in air.
