“…These combined mechanisms contribute to ZnO-150's exceptional selectivity in detecting NO 2 gas. 2,31 The ZnO-150 modified with apple pectin exhibits excellent performance in terms of response, sensitivity, selectivity, and repeatability. To verify the sensor's stability for environmental monitoring, the aging rate of the device was tested as an indicator of stability.…”

“…The outstanding selectivity of the ZnO-150 sensor can be attributed to two main factors. First, the abundance of V O defects in the ZnO-150 structure increases electron concentration, creating more active sites that enhance sensing performance. ,, Second, the strong electronic affinity of NO 2 (2.27 eV) results in a higher tendency to capture electrons from the sensing layer. These combined mechanisms contribute to ZnO-150's exceptional selectivity in detecting NO 2 gas. , …”
