One of the most significant drawbacks metal oxide (MOS) based chemiresistive gas sensors is requirement high operating temperature (250-450°C), which results in power consumption and shorter lifetime. To develop room (21±2°C) MOS sensors, sensing performance different nanostructures (i.e., tin (IV) (SnO2) nanoparticles (NPs), indium (III) (In2O3) NPs, zinc (ZnO) tungsten trioxide (WO3) copper (CuO) nanotubes (NTs), (In90Sn10O3 (ITO)) NPs) were systematically investigated toward toxic industrial chemicals (TICs) nitrogen dioxide (NO2), ammonia (NH3), hydrogen sulfide (H2S), carbon monoxide (CO), sulfur (SO2) volatile organic compounds (VOCs) acetone (C3H6O), toluene (C6H5CH3), ethylbenzene (C6H5CH2CH3), p-xylene (C6H4(CH3)2)) presence absence 400 nm UV light illumination. Sensing enhancement through photoexcitation strongly dependent on target analytes. Under at 76.0mW/cm2 intensity, NO2 was readily achieved where SnO2 NPs exhibited highest sensor response (S = 474.4 10ppmm (parts per million by mass)) with good recovery followed ZnO > In2O3 ITO NPs. Meanwhile, indirect bandgap n-type WO3 showed limited under illumination, whereas p-type CuO NTs relatively response. The improvements compared to other might be attributed number photogeneration electrons, rapidly reacted adsorbed NO2− species enhance reaction kinetics. a unique aromatic (e.g., p-xylene) maximum sensitivity 36mW/cm2 irradiation. Changing intensity from 0.0 36.4mW/cm2, 15.4-fold 6.3-fold 25ppmm 100ppmm p-xylene, respectively. optical excitation has effect CO, SO2, toluene, acetone.
