“…Nanofibers like Ag-decorated SnO 2 , PrFeO 3 , Pt-ZnO-In 2 O 3 , Au@WO 3 -SnO 2 , In-doped ZnSnO 3 , ZnO, and Ru-doped SnO 2 showed selective sensitivity to acetone at various operating temperatures (150-300 • C) [81][82][83][84][85][86][87]. Among them, Au@WO 3 -SnO 2 [84] [88][89][90][91][92][93][94]. These decoration of certain catalytic substrates may enhance acetone selectivity by varying the operating temperature.…”

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.

“…Extensive details for the gas sensor fabrication and testing were provided in our previous work [26,27]. To fabricate the gas sensor, a slurry was formed by mixing prepared samples and water, which was further coated onto an alumina tube (4 mm in length, 1.2 mm in external diameter and 0.8 mm in internal diameter) with two Au electrodes connected by Pt wires on both ends of the tube.…”

Lately novel strategies to enhance the sensing properties on iron oxide have been proposed to achieve high performance gas sensors for acetone detection. In this working report, the synthesis of iron-glycerate (Fe-Gly) using glycerol to combine with Fe3+ is first presented. Depending on the thermal treatment, this compound can evolve into γ-Fe2O3, α/γ-Fe2O3 and α-Fe2O3. α/γ-Fe2O3 shows better sensing performance as far as acetone detection is concerned. Using the dual phases of α/γ-Fe2O3 as a fundamental building block, their sensing properties were further improved using Ni doping and Ru nanoparticles functionalization. The high response and selectivity to acetone detection was ascribed to the synergistic effects of unique nanosheets, mixed phases, rich oxygen vacancies and excellent catalytic activity of Ru nanoparticles.

Acetone is one of the toxic, explosive, and harmful gases. It may cause several health hazard issues such as narcosis and headache. Acetone is also regarded as a key biomarker to diagnose several diseases as well as monitor the disorders in human health. Based on clinical findings, acetone concentration in human breath is correlated with many diseases such as asthma, halitosis, lung cancer, and diabetes. Thus, its investigation can become a new approach for health monitoring. Better management at the early stages of such diseases has the potential not only to reduce deaths associated with the disease but also to reduce medical costs. ZnO−based sensors show great potential for acetone gas due to their high chemical stability, simple synthesis process, and low cost. The findings suggested that the acetone sensing performance of such sensors can be significantly improved by manipulating the microstructure (surface area, porosity, etc.), composition, and morphology of ZnO nanomaterials. This article provides a comprehensive review of the state‐of‐the‐art research activities, published during the last five years (2016 to 2020), related to acetone gas sensing using nanostructured ZnO (nanowires, nanoparticles, nanorods, thin films, etc). It focuses on different types of nanostructured ZnO‐based acetone gas sensors. Furthermore, several factors such as relative humidity, acetone concentrations, and operating temperature that affects the acetone gas sensing properties‐ sensitivity, long‐term stability, selectivity as well as response and recovery time are discussed in this review. We hope that this work will inspire the development of high‐performance acetone gas sensors using nanostructured materials.
