Summary

Industrial exhaust, hazardous gases, and specialty gases pose significant impact to production safety, public health, and environmention. Gas sensors, by accurately identifying gas types and concentrations, enable real-time monitoring and early warning of multiple gases, thereby effectively preventing accidents and ensuring the safety of workers. Chalcogenide semiconductors have become a popular research direction due to their high specific surface area and abundant surface-active sites. The gas sensors based on these materials also have the characteristics of miniaturization and integration, making them highly potential for detecting low-concentration pollutants in complex industrial environments and for real-time monitoring requirements.

This Special Issue is dedicated to presenting the recent advancements of chalcogenide semiconductor materials in frontier applications in gas sensors, In particular, it focuses on a series of innovative achievements related to the synthesis of these materials, their working mechanisms, and the optimization of devices. Contributions addressing enhanced selectivity, long-term stability and practical deployment in environments are particularly encouraged. The goal is to provide a comprehensive forum for the research of chalcogenide semiconductor materials that bridge fundamental materials science with practical applications.

The special issue will cover topics related to the application of chalcogenide semiconductor materials in gas sensors and beyond, including but not limited to the following:
· Chalcogenide semiconductor sensors (MoS2, WS, etc.) for monitoring industrial exhaust, hazardous gases and specialty gases
· Nanostructured semiconductors and heterojunctions for enhanced performance
· Surface chemistry of chalcogenide semiconductors materials
· Selectivity improvement via doping, functionalization, or noble metal decoration
· Low-power, room-temperature, and flexible gas sensing devices
· Sensor arrays, electronic nose systems, etc. for industrial monitoring

    Abstract SF6 is the primary insulating and arc extinction medium in gas-insulated switchgear (GIS). Sulfur hexafluoride (SF6) decomposes to create diagnostic markers, such as sulfur dioxide (SO2), thionyl fluoride (SOF2), and hydrogen sulfide (H2S) when electrical problems occur, such as partial discharge and local overheating. Accurate quantification of these fault-marker gases is important for the early identification of insulation defects and the condition assessment of SF6-insulated equipment. Molybdenum disulfide (MoS2) is a well-known and atomically thin van der Waals semiconductor that has attracted considerable attention as a platform for gas-sensing applications. This is due to its large accessible surface area,… More >
