title: Ultrafast hydrogen sensing through hybrids of semiconducting single-walled carbon nanotubes and tin oxide nanocrystals.
abstract: We report an ultrafast and sensitive hydrogen (H(2)) sensing platform using semiconducting single-walled carbon nanotubes (SWCNTs) decorated with tin oxide (SnO(2)) nanocrystals (NCs). The hybrid SnO(2) 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.
