ZnO nanoarchitectures: Ultrahigh sensitive room temperature acetaldehyde sensor

- ZnO nanoarchitectures were facilely grown on glass substrates.
- Effect of doping on the formation of ZnO nanorods was investigated.
- Room temperature acetaldehyde sensor using ZnO nanoarchitectures has been reported.
- Ultrahigh sensitivity and selectivity observed for Co-doped ZnO.
