High-sensitivity, high-selectivity, and fast-recovery-speed triethylamine sensor based on ZnO micropyramids prepared by molten salt growth method

ZnO/BiFeO3 heterojunction interface modulation and rGO modification for detection of triethylamine

“…The main bond energies of TEA (C-N), isopropyl alcohol (C-C), ethanol/methanol (O-H), and acetone (CQO), are 307, 345, 458.8 and 798.9 kJ mol À1 , respectively. 44 Owing to the low bond energy of C-N, the TEA molecules are more easily oxidized than other gas molecules. In addition, changing the operating temperature can enhance selectivity because temperature affects the adsorption of gas at the surface of a material, that is, different gases have different optimum operating conditions.…”

Unique Pd/PdO–In2O3 heterostructures for the highly efficient detection of triethylamine

“…In the research of semiconductor TEA gas sensors, those based on different metal oxides have been widely studied, such as SnO 2 , 5 In 2 O 3 , 6 ZnO, 7 CuO, 8 etc. Among them, In 2 O 3 has been favored by researchers because of its good gas-sensing properties of TEA, however, there are still issues such as slow recovery time and high operating temperature.…”

Bicone-like ZnO structure as high-performance butanone sensor

“…However, the production of sensors with high selectivity, sensitivity, and low detection limit is still a challenge. Among the MOS, zinc oxide (ZnO), an n-type MOS, has demonstrated a great potential for the detection of several VOCs, including acetone [9], ethanol [10], acetaldehyde [11], formaldehyde [12], triethylamine [13], and so on. Nevertheless, to the best of our knowledge, there has been still no reports of ZnO as a chemiresistive sensor for butanone vapor.…”
