To maintain human and environmental health, it is essential to detect toxic gases. Over the years, researchers have often focused on industrial waste gases like CO, NO₂, H₂S, and NH₃. These hazardous gases can be detected by gas sensors.The conducting polymer, which has shown tremendous promise in room-temperature chemical gas detection due to the fact that its electrical conductivity may change when exposed to oxidative or reductive gas molecules, is one promising material for this sensor. Although in some circumstances, the decreased conductivity and significant attraction to volatile organic compounds and water molecules restrict sensitivity, stability, and gas selectivity, making them unsuitable for use as gas sensors. Inorganic sensitive materials provide various advantages in gas sensors, such as high sensitivity, rapid response to low-concentration analytes, a vast surface area, and changeable surface chemistry, which may supplement the sensing capabilities of conducting polymers. Along with their synergistic effects, there is a great deal of interest in combining inorganic sensitive materials with polymers for gas detection. This review focuses on the development of composite conducting polymers as gas-sensing materials. The implications of several factors affecting sensor performance, such as responsiveness, gas concentration, reaction time, and recovery time of conducting polymers, are highlighted. The function of inorganic nanomaterials in enhancing the gas-sensing performance of conducting polymers is discussed, as well as the development of conducting-inorganic composites including metal oxides, metal, and (carbon nanotube, and graphene. A comprehensive outlook on the topic of gas sensors containing conducting polymer-inorganic composites is delivered.

为了维护人类和环境的健康，检测有毒气体至关重要。多年来，研究人员经常关注工业废气，如 CO、NO ₂、H ₂ S 和 NH ₃. 这些有害气体可以通过气体传感器检测。导电聚合物在室温化学气体检测中显示出巨大的前景，因为当暴露于氧化性或还原性气体分子时其电导率可能会发生变化，是一种很有前途的材料这个传感器。尽管在某些情况下，电导率降低以及对挥发性有机化合物和水分子的显着吸引力限制了灵敏度、稳定性和气体选择性，使它们不适合用作气体传感器。无机敏感材料在气体传感器中具有多种优势，例如高灵敏度、对低浓度分析物的快速响应、广阔的表面积和多变的表面化学性质，这些可以补充导电聚合物的传感能力。连同它们的协同效应，将无机敏感材料与聚合物结合用于气体检测引起了极大的兴趣。本综述的重点是复合导电聚合物作为气敏材料的发展。重点介绍了影响传感器性能的几个因素的含义，例如响应能力、气体浓度、反应时间和导电聚合物的恢复时间。讨论了无机纳米材料在增强导电聚合物气敏性能方面的作用，以及包括金属氧化物、金属和（碳纳米管、石墨烯）在内的导电-无机复合材料的发展。对气体主题的综合展望交付包含导电聚合物-无机复合材料的传感器。
