Low-dimensional metal oxides have drawn significant attention across various scientific domains due to their multifaceted applications, particularly in the field of environment monitoring. Their popularity is attributed to a constellation of unique properties, including their high surface area, robust chemical stability, and remarkable electrical conductivity, among others, which allow them to be a good candidate for detecting CO, CO2, H2, NH3, NO2, CH4, H2S, and volatile organic compound gases. In recent years, the Sol-Gel method has emerged as a powerful and versatile technique for the controlled synthesis of low-dimensional metal oxide materials with diverse morphologies tailored for gas sensing applications. This review delves into the manifold facets of the Sol-Gel processing of metal oxides and reports their derived morphologies and remarkable gas-sensing properties. We comprehensively examine the synthesis conditions and critical parameters governing the formation of distinct morphologies, including nanoparticles, nanowires, nanorods, and hierarchical nanostructures. Furthermore, we provide insights into the fundamental principles underpinning the gas-sensing mechanisms of these materials. Notably, we assess the influence of morphology on gas-sensing performance, highlighting the pivotal role it plays in achieving exceptional sensitivity, selectivity, and response kinetics. Additionally, we highlight the impact of doping and composite formation on improving the sensitivity of pure metal oxides and reducing their operation temperature. A discussion of recent advances and emerging trends in the field is also presented, shedding light on the potential of Sol-Gel-derived nanostructures to revolutionize the landscape of gas sensing technologies.

“…TiO 2 could oxidize CO to CO 2 through both lattice oxygen vacancies (i.e., TiO 2−X ) and chemically adsorbed oxygen ions. Choudhary et al 110 prepared Y doped ZnO-CdO (YZC) by sol−gel method and obtained a CO 2 sensor that could work at room temperature. With the increased content of Y dopants in YZC, the morphology of YZC changed from cauliflower-like structure to nanoflake structure, and then to granular aggregate.…”

With the increasing popularity of battery technology, the safety problems caused by the thermal runaway of batteries have been paid more attention. Detecting the gases released from battery thermal runaway by gas sensors is one of the effective strategies to realize the early safety warning of batteries. The inducing factors of battery thermal runaway as well as the types and mechanisms of the gases generated at each reaction stage are first reviewed. According to the amount and starting time of gas release, five gases suitable for early detection of battery thermal runaway are mainly introduced, including hydrogen (H 2 ), carbon monoxide (CO), carbon dioxide (CO 2 ), ethylene (C 2 H 4 ), and methane (CH 4 ). The application prospects of various gas-sensing technologies in the detection and early warning of battery thermal runaway are further evaluated. Benefiting from the superiorities of small size, high sensitivity, and stable performance, the resistive gas sensors are considered as promising candidates in this field, and their sensing mechanisms are also described in this review. In addition, the applicability and optimization strategies of gas sensors for the detection and early warning of battery thermal runaway are further reviewed systematically, on the basis of various aspects including sensing material, material design, sensing performance, etc. Finally, the potential directions and key points for the future development of gas sensors in the detection and early warning of battery thermal runaway are proposed.
