“…Recently, ternary oxide-based ethanol sensors have been investigated by many researchers [85,109,118,123,124,125,126]. Zhou et al prepared ZnSnO 3 hollow cubes using the co-precipitation method, followed by alkali etching and annealing under inert conditions [109].…”

Volatile organic compounds (VOCs), which originate from painting, oil refining and vehicle exhaust emissions, are hazardous gases that have significant effects on air quality and human health. The detection of VOCs is of special importance to environmental safety. Among the various detection methods, chemoresistive semiconductor metal oxide gas sensors are considered to be the most promising technique due to their easy production, low cost and good portability. Sensitivity is an important parameter of gas sensors and is greatly affected by the microstructure, defects, catalyst, heterojunction and humidity. By adjusting the aforementioned factors, the sensitivity of gas sensors can be improved further. In this review, attention will be focused on how to improve the sensitivity of chemoresistive gas sensors towards certain common VOCs with respect to the five factors mentioned above.

“…Alcohols, as an organic additive, often are widely used to obtain materials with special morphology and size. For example, using ethanol as additive, pyramid-SnO 2 [43], nanostructure α-Fe 2 O 3 [44], ZnSnO 3 hollow microspheres [45], Bi 2 WO 6 hollow nano-spheres [46] and thin plate-like MgAl-LDH [18] were prepared.…”

In this study, water-n-BuOH mixed solvents were used to synthesize the ZnAl-layered double hydroxides (ZnAl-LDHs) via hydrothermal method. The XRD, FT-IR, SEM, ICP and CHN analyses revealed that the type of intercalated anions, the layer Zn/Al ratios, and morphologies of the LDHs depended on the ratio of V(water)/V(n-BuOH) in the mixed solvents. When the ratio of V(water)/V(n-BuOH) is 3 or 0.3, the as-prepared LDHs had 3D "silk flowers" (ZnAl-LDH-3) or "Sedimentary rock" morphology (ZnAl-LDH-0.3). Adsorption properties of dyes on calcined LDHs were studied. Compared with ZnAl-LDO-0.3 and ZnAl-LDO-w (calcined from the LDHs obtained in pure water), ZnAl-LDO-3 showed much better adsorption efficiency for anionic dyes thanks to its much larger BET-specific surface area. The sorption kinetics for dyes was appropriately described by the pseudo-second-order model and sorption isotherms can be fitted more satisfactorily by the Langmuir model. With the increasing concentrations of dyes from 10mg/L to 400mg/L, the maximum absorption capacities of ZnAl-LDO-3 were 1540mg/g (2.21mmol/g) for congo red, 1153mg/g (3.52mmol/g) for methyl orange and 390mg/g (0.63mmol/g) for active red (X-3B), respectively. The adsorption dyes onto the external surface is still the main mechanism for LDO adsorbents. The ZnAl-LDO-3 was a potential adsorbent for dyeing wastewater treatment.

“…Table 1 shows the formaldehyde sensing performances of various ZnSnO 3 based gas sensors. Obviously, the response of the porous ZnSnO 3 nanocubes is much higher than those of mesoporous ZnSnO 3 hollow microspheres, 48 ZnSnO 3 nanosheets, 49 ZnSnO 3 /wt 10% SnO 2 concave microcubes, 50 porous ZnSnO 3 cubes, 35 ZnSnO 3 hollow microspheres, 51 ZnSnO 3 hollow nanocubes, 52 hierarchical ZnSnO 3 nanocages 53 and hollow ZnSnO 3 cubic nanocages. 54 The gas sensing response enhancement may be attributed to the porous structure and the more numerous active centers obtained from the enhanced oxygen vacancy defects on the porous nanostructure, as shown in the PL spectra.…”
