This work presents a novel nanostructured material SnO2/multiwalled carbon nanotubes (MWCNTs) as sensing film for the detection of acetone and ethanol vapors. The fabrication SnO2/MWCNT chemoresistive sensors demonstrates cost-effective hydrothermal method using centrifugation technique. investigation synthesized SnO2/MWCNTs nanocomposite represents various techniques, such scanning electron microscopy (SEM), transmission (TEM), energy-dispersive X-ray (EDX) elementary analysis, EDX mapping, diffraction (XRD) analysis. sensor exhibits rapid response/recovery behavior toward (53/5 s) (86/3 while showing satisfactory values responsiveness (Sact = 90.5 Setn 21, n 100 ppm). low limit these vapors is assigned concentration 1 ppm, where discernible responses are elicited. Thus, production efforts have yielded high-end volatile organic compound (VOC) detector, highly suitable human technological engineering activity.

A UV-Photon-Energy-Integrated Gas Sensor Based on Pt-Nanoparticle-Decorated TiO2 Nanorods for Room-Temperature Hydrogen Detection

Chemosensors, Год журнала: 2025, Номер 13(5), С. 177 - 177

Опубликована: Май 11, 2025

Hydrogen sensors play a crucial role in ensuring safety various industrial applications. In this study, we demonstrated the use of room-temperature hydrogen gas sensor based on Pt-nanoparticle-decorated TiO2 nanorods (TiO2 NRs/Pt NP). The NRs were synthesized via hydrothermal method, followed by Pt deposition using sputtering and thermal annealing. Under UV illumination, NR/Pt NP exhibited remarkable response 2.4 at 1% concentration, which is approximately 5.9 times higher than that bare measured dark. This enhancement attributed to synergistic effect NPs, promote charge separation spillover for oxygen molecules, activation, generates additional carriers. Moreover, stable reliable detection concentrations up without need external heating, underscoring its practical applicability under ambient conditions. These results demonstrate NP, combined with provide promising approach highly sensitive detection, offering significant potential monitoring energy systems.
