Dip-coating decoration of AgO nanoparticles on SnO nanowires for high-performance HS gas sensors.

SnO nanowires (NWs) are used in gas sensors, but their response to highly toxic gas HS is low. Thus, their performance toward the effective detection of low-level HS in air should be improved for environmental-pollution control and monitoring. Herein, AgO nanoparticle decorated SnO NWs were prepared by a simple on-chip growth and subsequent dip-coating method.
