英文摘要	The rational interaction between the oxide surfaces and aimed gas is favorable for enhancement in gas-sensing (including rapid response and recovery rate, remarkable response value, and excellent selectivity). Herein, we have prepared acidic alpha-MoO3 nanorods through a facile hydrothermal route. The as-obtained MoO3 nanorods possess about 10 mu m in length and around 200-300 nm in diameter, respectively. The gas sensor fabricated using these MoO3 nanorods exhibits an apparent response to triethylamine (TEA) vapor with an actual detection concentration as low as 0.1 ppm at its optimal working temperature of 300 degrees C. The response time for detecting 100 ppm TEA is only 4 s, and the recovery time is less than 2 min (88 s). Moreover, the sensor shows an extremely remarkable selectivity towards TEA against other interfering gases, such as methanol, ethanol, isopropanol, acetone, toluene, and ammonia. The impressive TEA sensing of these MoO3 nanorods could be determined by suitable interaction between TEA molecules and the MoO3 surfaces (including base/acid attractive force, highly active lattice oxygen for catalytical oxidation of TEA, and fast adsorption/desorption kinetics at certain temperature). This paper provides an avenue for designing high-performance gas sensor from perspective of understanding the interaction between aimed gas and material surfaces. (C) 2018 Elsevier B.V.
