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

Analytical Chemistry, Journal Year: 2025, Volume and Issue: unknown

Published: March 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

Rational Design of PdPt Nanoalloys Sensitized Mesoporous SnO₂ for High‐Performance Methane Sensing Applications

Advanced Materials Technologies, Journal Year: 2025, Volume and Issue: unknown

Published: March 8, 2025

Abstract Methane (CH 4 ) serves as a commonly utilized fuel gas in various industrial and everyday settings. Given its flammable, explosive, greenhouse nature, the real‐time monitoring of concentration air holds vital importance across practical applications. The tetrahedral structure methane molecules features high bond energies, posing significant challenge for chemical detection over metal oxide‐sensitive layers. In this research, multicomponent assembly method is used to synthesize ordered mesoporous tin oxide (SnO 2 with uniform large mesopores (≈ 10 nm) pore wall functionalized Pd x Pt nanoalloys 2.5 nm), due unusual C–H activation capabilities semiconducting properties SnO , obtained Pt@m‐SnO fabricate sensors which showcases wide applicability range detecting concentrations ranging from 50 20 000 ppm at 400 °C, it yields substantial CH response 9.19 (1000 ppm) an ultralow limit value 175.9 ppb. Furthermore, sensor successfully incorporated into portable device, evidencing capability accurate real‐world scenarios.
