“…It is observed that the response time, which are defined as the time for reaching 90% of the full response of sensor, are in the range of 7-30 s, while the 90% recovery time are ranging from 45 to 290 s for both ZnO samples, without requiring any external stimuli, which are better than some other results [32]. Typically, response and recovery time of sensors are usually about 100 s and more than 500 s [36]. Owing to our compact sensor system as well as our oxygen-ambient-growth samples, both response and recovery time are greatly improved in this work.…”

Metal oxide 1D nanowires are probably the most promising structures to develop cheap stable and selective chemical sensors. The purpose of this contribution is to review almost two-decades of research activity at the Sensor Lab Brescia on their preparation during by vapor solid (n-type In2O3, ZnO), vapor liquid solid (n-type SnO2 and p-type NiO) and thermal evaporation and oxidation (n-type ZnO, WO3 and p-type CuO) methods. For each material we’ve assessed the chemical sensing performance in relation to the preparation conditions and established a rank in the detection of environmental and industrial pollutants: SnO2 nanowires were effective in DMMP detection, ZnO nanowires in NO2, acetone and ethanol detection, WO3 for ammonia and CuO for ozone.
