In parallel with rapid development in the industry, the amount of toxic and greenhouse gases released into the atmosphere is increasing daily. Therefore, it is of great importance to detect, capture, and eliminate toxic and greenhouse gases, to leave a cleaner environment to future generations. From the past to the present, many studies have been carried out to successfully realize and improve the processes of detecting, capturing and eliminating toxic and greenhouse gases. Gas sensing technology is crucial for environmental monitoring, industrial safety, and healthcare. As a sensing material, transition metal dichalcogenides (TMDCs) have been promising owing to their electronic and chemical properties. It has been theoretically determined that Janus materials, which have been experimentally synthesized in recent years, have promising gas-sensing behaviors. In the present work, to better understand the gas-sensing properties of Janus TMDC materials, theoretical studies in the literature have been reviewed in detail. It consists of the adsorption behaviors of various gases for different sides of Janus materials, and the effect of defects, surface doping/functionalization, strain, and out-of-plane electrical field on sensing mechanisms of Janus materials. As a result of this review, it can be concluded that TMDC Janus materials with surface modifications, strain, and external electric field are promising in gas detection applications.
