Abstract The future of environmental monitoring, medical diagnostics, and industrial safety depends on developing room‐temperature, long‐term operable, stable, miniaturized, ultrahigh‐performance sensors integrated into the Internet Things (IoT). While noble metals high‐entropy alloys (HEAs) lead in addressing limitations conventional transition‐metal dichalcogenides (TMDs) like MoS₂, they face challenges such as high‐cost, limited availability, fabrication complexity. To address this, multifunctional, cost‐effective, humidity‐insensitive novel phase Ti₀.₅Zn₀.₅ (TiZn) alloy nanoparticle‐decorated MoS₂ nanosheets (MoS₂_NP) is developed for ultra‐selective highly sensitive triethylamine (TEA) vapor detection at room temperature (RT). This exhibited a 24‐fold increase response compared to with high signal‐to‐noise ratio, negligible humidity interference, sensitivity 9.92 × 10⁻⁵ ppm⁻¹ RT, limit 48 ppm. enhanced catalytic activity defect concentration, reduction edge oxidation resulting strong Fermi‐level pinning, relatively adsorption energy target gas‐specific carrier‐type response, demonstrating potential binary nanoparticles (NPs) decorative materials sensing applications. superior performance sensor led development TEA prototype interfaced mobile device via IoT continuous enhancing practicality usability by offering immediate access critical information.
