We report an ultrafast and sensitive hydrogen (H-2) 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% H-2 under room temperature and can fully recover within a few minutes in air.
