“…n -Butanol is now used widely as a solvent, extraction agent, or surfactant for paints, plasticizers, and biochemical drugs. − However, due to its stimulating and narcotic nature, n -butanol steam may cause drowsiness and dizziness and may damage eyes, respiratory system, and skin. − In addition, n -butanol is flammable and explosive when mixed with other organic solvents such as ethanol and diethyl ether . Therefore, the development of the n -butanol sensor is very meaningful to workers’ health and production safety.…”

In2O3 nanoparticles decorated ZnO hierarchical structures with excellent n-butanol-sensing performance were successfully fabricated by the one-pot sol–gel method. The formation process of the unique In2O3–ZnO hierarchical structure was investigated through experiments. The addition of indium was a crucial factor for the morphology and structure of the final product. The influence of the addition of indium on the sensor properties of the In2O3–ZnO hierarchical structure was examined systematically. The optimum indium–zinc ratio was 1:3. Sensor responses of the In2O3–ZnO (1:3) heterostructures toward 10 and 100 ppm n-butanol reached 18 and 218.3 at 260 °C. The response–recovery times toward 10 ppm n-butanol were 1 and 5 s. The gas-sensing mechanism was investigated based on the X-ray photoelectronic spectroscopy, photoluminescence spectroscopy, electron paramagnetic resonance spectroscopy, and UV–vis diffuser reflectance spectroscopy analyses. The improved gas-sensing performance of In2O3–ZnO was ascribed mainly to the unique microstructure and the surface decoration by In2O3 nanoparticles.

“…The specific surface area of 0.5% Pt‐functionalized TiO 2 has increased when comparing with that of pure TiO 2 , for the specific surface area is calculated to be 168.10 and 147.17 m 2 g −1 , respectively. The numeric values are higher than that of ZnO, SnO 2 , and Fe 2 O 3 materials as gas‐sensing materials reported in other literature . This might be a point to explain the reason why 0.5% Pt‐functionalized TiO 2 based gas sensor shows more superior gas‐sensing performance than pure TiO 2 .…”

A facile hydrothermal method is used to prepare Pt-functionalized nanoporous TiO 2 nanoparticles. These are used as gas-sensing material in sensors, fabricated according to the indirect heating method. Gas-sensing performance of the sensors is investigated by testing their gas response to acetone, which exhibits favorable selectivity, good gas response value, fast response/recovery time, low detection concentration and good long-term stability to acetone. Gas response β was defined as the ratio of R a /R g , where R a and R g are the resistance values of gas sensor exposed in air and objective gas, respectively. Among all these as-prepared gas sensors, the 0.5% Pt-functionalized TiO 2 based gas sensor shows the highest gas response value of 29.51-200 ppm acetone at 300 C, and the gas response value is 5.2 times higher than that (5.67) of pure TiO 2 based gas sensor. It also has excellent selectivity to acetone when comparing with toluene, n-butanol, isopropanol, ethanol, and methanol. The large specific surface area (168.101 m 2 g À1 ) provides enough contacting interface between gas and the as-prepared materials, then the gas molecules could be broken into CO 2 and H 2 O by the active adsorbed oxygen species. The present results of the Ptfunctionalized TiO 2 based gas sensors illustrates their potential application in detecting acetone.

Environmental pollution related to volatile organic compounds (VOCs) has become a global issue which attracts intensive work towards their controlling and monitoring. To this direction various regulations and research towards VOCs detection have been laid down and conducted by many countries. Distinct devices are proposed to monitor the VOCs pollution. Among them, chemiresistor devices comprised of inorganic-semiconducting materials with diverse nanostructures are most attractive because they are cost-effective and eco-friendly. These diverse nanostructured materials-based devices are usually made up of nanoparticles, nanowires/rods, nanocrystals, nanotubes, nanocages, nanocubes, nanocomposites, etc. They can be employed in monitoring the VOCs present in the reliable sources. This review outlines the device-based VOC detection using diverse semiconducting-nanostructured materials and covers more than 340 references that have been published since 2016.
