A review on MXene and its nanocomposites for the detection of toxic inorganic gases

Manoj Devaraj et al.

Summary: In the search for viable candidates for pollutant gas sensing, two-dimensional material transition metal carbides (MXenes) have attracted great attention for their outstanding physical and chemical properties. The unique 2D layered structure of MXenes, with high conductivity, mechanical strength, and adsorption properties, allows for strong interactions with gaseous molecules and holds promise for developing ideal gas sensing devices. This review focuses on recent achievements in MXene-based materials for room temperature inorganic gas sensors and provides a comprehensive understanding through theoretical and experimental studies. The review discusses the properties and advantages of MXene as a sensing material compared to other 2D materials, the unique advantages of chemiresistive based sensors, the demerits of other detection methods, the structural design of MXene for improved sensing performance, the interaction between MXene and adsorbed gases, and possible sensing mechanisms. The review concludes with an overview of current progress, opportunities, and perspectives for the future improvement of MXene in gas sensors.
