“…The results show that the nanotubes exhibit gas responses of 20% at 1 ppm and 84% at 5 ppm when operated at a temperature of 200 1C. These sensitivity levels are higher than those of other materials such as ZnO nanosheets, 90 ZnO nanoneedles, 91 a bunch of ZnO nanowires, 45 and CuO-ZnO flakes. 46 These findings imply that 1D ZnO nanotubes have the potential to be employed as an NO 2 sensor device.…”

This article explored the influence of lithium on cobalt-doped ZnO thin films fabricated via the sol-gel spin coating technique for NO2 gas sensing applications. The abundance of oxygen vacancies in ZnO can be proven by scanning electron microscopy, four-probe Hall measurements, photoluminescence spectroscopy, UV-visible spectroscopy, and X-ray photoelectron spectroscopy. The presence of lithium plays a crucial role in generating more oxygen vacancies in Co-doped ZnO was discussed. Among the fabricated samples, (Li-Co) co-doped ZnO exhibits better sensitivity (2940.17%), selectivity, repeatability, and stability (after 90 days) toward 75 ppm NO2 gas.

“…Metal oxide semiconductors (MOS) such as ZnO [9], NiO [10], SnO 2 [11], WO 3 [12], etc., are excellent gas sensitive materials due to their unique structures and exceptional electrical properties [13,14]. However, these materials show good gas-sensitive properties to NO 2 only at high temperatures.…”

In this paper, VO2 ultrathin nanosheets array / ZnO nanoparticles composite structures with uniform sizes were synthesized by the combination of hydrothermal method and water bath method. The effect of ZnO content on the room temperature NO2 sensing performance of VO2 (B) ultra-thin nanosheet arrays was studied. The response to NO2 was enhanced by up to 200% at the optimized ZnO content in ZnO/VO2 composite structure. The performance improvement is related to deep level electron transfer and barrier height modulation mechanism based on ZnO/VO2 n-n heterojunction. Therefore, activating VO2 nanosheets with zinc oxide particles may be a promising method for designing and manufacturing high-performance room temperature gas sensors.
