In this work, WO3/TiO2 core–shell (C-S) nanowires (NWs) were successfully synthesized by the coaxial electrospinning method and subsequent high-temperature calcination treatment. After some microscopic structural characterizations, although prepared WO3–TiO2 TiO2–WO3 C-S NWs displayed quite different surface morphologies, both of shell coatings uniform their typical thicknesses extremely close, with mean values 22 20 nm, respectively. gas sensing tests, exhibited good selectivity towards triethylamine (TEA) without significant interfering gases. Compared bare WO3 TiO2 NWs, showed better performance. Specifically, optimal operating temperature response to 100 ppm TEA 130 °C 106, which reduced 70 increased 5.73 times compared WO3, Obviously, nanostructures contributed improving performance materials TEA. Finally, hypothetical mechanisms proposed, expected have important reference significance for design target products applied sensing.

Abstract Formaldehyde is a frequent indoor pollutant that poses risk to human and environmental health suspected be carcinogen. However, achieving high sensitivity selectivity for real‐time applications remains challenging. In this study, room‐temperature operated formaldehyde chemiresistor developed by cerium dioxide/indium oxide (CeO 2 /In O 3 ) nanocomposite exclusive detection. The synthesized using hydrothermal, forming CeO nanospheres grown on nanocubes. This unique structure enhances the sensing capabilities of , allowing it detect in 1–50 ppm range, 0.157 detection limit earned. sensor exhibits an impressive response 175.05 at 50 room temperature shows responsiveness various other substances, instance, methanol, ethanol, aniline, benzene, toluene, acetone, ammonia. Additionally, demonstrated moderate selectivity, sensitivity, stability, speedy response/recovery times, resilience humidity. work presents promising strategy formaldehyde.
