In this work we have studied the NO2 sensing properties of the sensors with tetrapods. The tetrapods that were used in the production were obtained by CVD route, and their structural analysis was carried out using SEM, XRD and EDX methods. The sensors were produced by a different method that the one mentioned in our another work, and additional electrical I-V characterization was carried out. As well as in the previous work the sensors were tested for 50 ppm sensitivity, by using computer controlled gas flux system, in NO₂ at 200°C, and in ambient air to model the normal working conditions more closely. It was found that the sensors have a good sensitivity to the NO₂ gas. All of the sensors showed a great reversibility and it was found that the recovery time was perfectly low. After this experiment the same sensors were tested with other different gases for several times. And no other problems in sensing ability were seen.
