Interest in the importance of gas sensing devices has increased significantly due to their critical function in monitoring the environment and controlling pollution, resulting in an increased market demand. The present review explores perovskite La-Fe-O based gas sensors with a special focus on LaFeO and evaluates their sensitivity to a diverse range of practical target gases that need to be monitored. An analysis has been conducted to assess different routes not only of synthesizing LaFeO material but also of characterization with the targeted use for their gas sensing abilities. Additionally, a comprehensive analysis has been performed to explore the effect of introducing other elements through doping. In view of the LaFeO sensing performance, more common gases like acetone, ethanol, methanol, formaldehyde, NO , and CO have been targeted. In addition, a discussion on uncommon gases such as CO, SO, TEA, CH, CH, and others is also made to give a complete picture of LaFeO-based gas sensors. The summary and conclusion section of the study addresses the primary obstacles in the synthesis process, the variables that restrict the sensing capabilities of LaFeO, and its commercial fulfillment.
由于气敏装置在监测环境和控制污染方面的关键作用，其重要性已引起人们极大关注，市场需求也随之增加。本综述探讨了基于钙钛矿La-Fe-O的气敏传感器，特别关注LaFeO，并评估了它们对各种需要监测的实际目标气体的灵敏度。不仅对合成LaFeO材料的不同途径进行了分析，还对其用于气敏能力的表征途径进行了分析。此外，还进行了全面分析，以探讨通过掺杂引入其他元素的影响。鉴于LaFeO的传感性能，已将丙酮、乙醇、甲醇、甲醛、NO 、CO等更常见的气体作为目标。此外，还对CO、SO、TEA、CH、CH等不常见气体进行了讨论，以全面了解基于LaFeO的气敏传感器。研究的总结和结论部分阐述了合成过程中的主要障碍、限制LaFeO传感能力的变量及其商业化实现情况。
