MXenes have shown exceptional electrochemical properties and demonstrate great promise in chemiresistive gas analysis applications. However, their sensing applications still face low sensitivity specificity, slow response, poor stability among the many challenges. Herein, a novel synthetic approach is reported to produce single-atom Pt (Pt SA)-implanted Ti3C2Tx MXene nanosheets as channel field-effect transistor (FET) sensors. This pioneer study of catalysts loaded on for detection, which demonstrates that SA can greatly enhance performance pristine Ti3C2Tx. The SA-Ti3C2Tx sensor exhibits high specificity toward ppb level (a detection limit 14 ppb) triethylamine (TEA) with good multicycle performance. Moreover, mechanism density functional theory (DFT) simulation show chemical sensitization effect TEA adsorption enhancement from highly catalytic uniformly distributed lead enhanced performances. work presents new prospect applications, will promote development cutting-edge techniques public health environment.
