“…Figure 13 shows the energy band diagram of UV-assisted ZnO sensing at 25 °C. The fabrication of the 1D Zn 2 SnO 4 nanowire and 2D ZnO nanosheet hybrid hierarchical structures for use in triethylamine gas sensors was investigated and reported by Liu et al [64]. In that work, a unique Zn 2 SnO 4 -ZnO hierarchical structures composed of 1D Zn 2 SnO 4 nanowires and two-dimensional ZnO nanosheets were successfully synthesized via a facile hydrothermal method combined with calcination [64].…”

“…It also showed that the obtained Zn 2 SnO 4 -ZnO hierarchical structures exhibited improved gas sensing performance toward triethylamine (TEA) in terms of a low operating temperature, high sensor response, and good selectivity, comparing with pure Zn 2 SnO 4 nanowires and pure ZnO nanosheets [64]. The results of the study showed that the gas sensing test results revealed that the sensor response of Zn 2 SnO 4 -ZnO sensor reached 175.5 toward 100 ppm TEA at an optimum operating temperature of 200 °C, which was approximately 47.4 and 30.8 times higher than that of pure Zn 2 SnO 4 and pure ZnO, respectively [64]. In addition, the Zn 2 SnO 4 -ZnO hierarchical structures exhibited good selectivity and long-term stability to TEA, suggesting their potential application in advanced TEA gas sensors [64].…”

This paper presents the recent advances of the ZnO nanowires based sensors. ZnO has gained a substantial interest in the research areas of the wide band gap semiconductors due to its unique electrical, optical and structural properties. ZnO is considered as one of the major candidates for several electronic and photonic applications. ZnO is considered as a potential contender in optoelectronic applications such as solar cells, surface acoustic wave devices, and ultraviolet (UV) emitters. ZnO as a nanostructured material exhibits many advantages for nanodevices. ZnO nanostructured material has the ability to absorb the UV radiation. ZnO nanowires have received a considerable attention due to the morphological changes with doping. ZnO nanowires are very attractive material for nano-sensors due to their properties induced by the quantum size effects. Recently, ZnO nanowires based devices have gained much attention due to their various potential applications in nanoelectronics devices including gas sensors, nanogenerators, and nano-lasers. The recent aspects of ZnO nanowires based sensors devices are presented and discussed.

There is rapid growth in the global gas sensor market driven by new regulations for industrial emission control and residential environments and increasing demand for portable devices. Nanosensors promise to be the next generation gas sensors for the direct detection of chemical species due to their ultrahigh sensitivity, fast response, ultralow weight, and low power consumption. However, transitioning nanosensors from basic research or prototype projects to commercial products encounters two major technical challenges: difficulty in scale up and inability to demonstrate real‐world use in changing humidity and temperature conditions. The advances in addressing these two technical challenges in recent literature are surveyed. The most common 1D nanomaterials in R&D for gas sensing, metal oxides, and carbon nanotubes, as well as less common metal nanowires and psudo‐1D crystals made from charge‐transfer complexes (CTCs) are included. This review delves into the specifics of each of these 1D nanomaterials for gas sensing applications, their synthesis and deposition, sensing performance, and commercial development in the last 5 years. It highlights the scalability of one‐step electrodeposition of CTC nanowires on prefabricated electrodes, at room temperature, and from solution in making gas nanosensors.
