Rapid and Sensitive Detection of 2-Ethylhexanol Vapor Utilizing Mesoporous Neodymium-Doped Indium Oxide for Real-Time Monitoring of Overheated Electrical Cables

Analytical Chemistry, Год журнала: 2025, Номер unknown

Опубликована: Март 24, 2025

Rapid and sensitive detection of 2-ethylhexanol vapor, a critical indicator overheating in electrical cables, is essential for the early warning potential fires. However, traditional chemiresistive gas sensors are inadequate real-time owing to its chemical stability. Herein, sensor based on mesoporous Nd-doped In2O3 designed rapid ppb-level vapor. The exhibits high response (22.8@1 ppm), excellent sensitivity (4.7 ppm–1), short time (29 s), low limit (760 ppb). After Nd doping, approximately 20 folds higher than that sensor. Furthermore, wireless sensing device has been developed enable monitoring cable overheating. outstanding performance can be attributed neodymium doping within framework, which enhances accessibility active sites interface materials, increases concentration surface-adsorbed oxygen at gas–solid interface, improves adsorption capacity 2-ethylhexanol. This work showcases an efficient semiconductor metal oxide capable rapidly sensitively detecting parts per billion levels induced by demonstrating significant

Advanced Sensor Research, Год журнала: 2024, Номер unknown

Опубликована: Июнь 16, 2024

Abstract The volatile aroma released from agricultural products is closely related to the health status and quality of their growth, thus endowing detection with great significance. For example, dynamic variation chemical composition a banana during growth process can reflect its ripeness. Also important for monitoring storage precisely swiftly identify compounds produced by mildew in rice wheat. In this endeavor, current technologies such as gas chromatography‐mass spectrometry method (GC‐MS) cannot meet pressing needs smart agriculture terms real‐time monitoring, cost‐effectiveness, sensitivity, speed, thereby necessitating alternative strategies simultaneously satisfy these requirements. Aiming provide an overall development trend field, paper summarizes existing including GC‐MS, E‐nose, sensory analysis respective shortcomings challenges, then proposes application prospects. This work effectively enrich reliable methods fragrance while promoting long‐run agriculture.
