Au-doped zinc oxide nanostructure sensors for detection and discrimination of volatile organic compounds
Pure and 10% w/w Au-doped zinc oxide (ZnO) nanostructure sensors were produced and used as sensing devices in a portable electronic nose (E-nose). The nanosensors were prepared using thermal oxidation technique with sintering temperature at 700°C under oxygen atmosphere at a flow rate of 500 mL min-...

Kerdcharoen Engineering Materials Science Physics and Astronomy Pure and 10% w/w Au-doped zinc oxide (ZnO) nanostructure sensors were produced and used as sensing devices in a portable electronic nose (E-nose). The nanosensors were prepared using thermal oxidation technique with sintering temperature at 700°C under oxygen atmosphere at a flow rate of 500 mL min-1. The sensors were demonstrated to be sensitive to various volatile organic compounds (VOCs), especially ethanol vapour.
