Facile Fabrication of Oxygen‐Enriched MXene‐Based Sensor and Their Ammonia Gas‐Sensing Enhancement

Various sensing materials have been demonstrated to increase the precision of technology. Nevertheless, this complicates fabrication process for integration obtain devices that can simultaneously accommodate various gas detectors, like electronic nose. The study here focuses on exploring response different functionalization specific provide an alternative way achieve selective multiple gases. Triethoxysilylpropyl succinic anhydride silane (TESPSA) was introduced 2D material MXene-Ti3C2Tx form carboxylic acid terminated MXene (COOH-Ti3C2Tx) and alternately coated with polyaniline (COOH-Ti3C2Tx/PANI). This modification doubled up binding sites improved strength Ti3C2Tx surface NH3 molecules. 5CC-COOH-Ti3C2Tx/PANI sensor prepared from five coating cycles showed highest sensitivity (214.70 %) fast rate at 80 ppm (1.75 % s-1). Therefore, signal responses same will allow possible array fingerprint-like map recognition in presence mixed
