Ethanol chemiresistor with enhanced discriminative ability from acetone based on Sr-doped SnO2 nanofibers

- Sr-doped SnO2 nanofibers have been successfully obtained via electrospinning and calcination.
- Sr-doped SnO2 nanofibers show high response and rapid response/recovery behavior to ethanol.
- Sr-doped SnO2 nanofibers exhibit good discriminative ability to ethanol from acetone.
- Sr-doped SnO2 nanofibers display good selectivity to some reducing gases.
