| Popis: | Currently, the gas sensor market is worth USD 2.33 billion. It is forecasted that the growth of compound annual rate value willing to be 8.7% within the length from 2021 to 2028. The commercial prospects of the semiconducting metal oxide-based gas sensor are limited due to high-temperature operation, higher power consumption, short-term stability, and sensitivity to humidity. Amongst all, tin oxide-based sensors are most commercialized owing to their tunable physicochemical properties. Moreover, the bottlenecks of elevated temperature operation, stability, and selectivity can be catered to by developing its hybrid nanocomposites with other organic and inorganic materials. The multi-interactions, surface functionalization, and formation of heterojunctions in SnO2 nanocomposites enhance their interaction with analyte molecules resulting in excellent sensing performances. This review aims to provide insights into various synthesis strategies to fabricate SnO2 and its hybrid nanocomposites. The advancements in physicochemical properties and structural chemistries are discussed in terms of various spectroscopic analyses. Further, the development in sensor devices using hybrid SnO2 nanoparticles and their sensing properties towards different gasses and VOCs are discussed. This review focuses on studies dealing with low and moderate-temperature gas detection through SnO2 based nanosystems. A comprehensive comparison and correlation of all the mentioned sensing results have been concluded to propose suitable conditions, hybrid SnO2 nanocomposite for superior gas sensing applications. |
