Abstract Methane (CH 4 ) serves as a commonly utilized fuel gas in various industrial and everyday settings. Given its flammable, explosive, greenhouse nature, the real‐time monitoring of concentration air holds vital importance across practical applications. The tetrahedral structure methane molecules features high bond energies, posing significant challenge for chemical detection over metal oxide‐sensitive layers. In this research, multicomponent assembly method is used to synthesize ordered mesoporous tin oxide (SnO 2 with uniform large mesopores (≈ 10 nm) pore wall functionalized Pd x Pt nanoalloys 2.5 nm), due unusual C–H activation capabilities semiconducting properties SnO , obtained Pt@m‐SnO fabricate sensors which showcases wide applicability range detecting concentrations ranging from 50 20 000 ppm at 400 °C, it yields substantial CH response 9.19 (1000 ppm) an ultralow limit value 175.9 ppb. Furthermore, sensor successfully incorporated into portable device, evidencing capability accurate real‐world scenarios.
