Detecting and distinguishing between hazardous gases with similar odors by using conventional sensor technology for safeguarding human health ensuring food safety are significant challenges. Bulky, costly, power-hungry devices, such as that used gas chromatography-mass spectrometry (GC-MS), widely employed sensing. Using a single chemiresistive semiconductor or electric nose (e-nose) to achieve this objective is difficult, mainly because of its selectivity issue. Thus, there need develop new materials tunable versatile sensing characteristics. Phase engineering two-dimensional better utilize their physiochemical properties has attracted considerable attention. Here, we show MoSe
