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.

Increasing the proportion of clean energy within structure is a crucial strategy for achieving transformation. Hydrogen and ammonia, as leaders in technologies, have garnered significant global attention. The combination hydrogen ammonia has emerged novel form storage, transportation, conversion; however, safety aspects their application process warrant closer Research on been conducted extensively, with particular focus leakage, diffusion, combustion, explosion processes. Both theoretical research engineering applications advanced significantly. In particular, detection technology, primarily based electrical measurement, matured considerably, while schlieren imaging-based flow field visualization technology progressing steadily. contrast, concerning remains its early stages. leakage diffusion characteristics predominantly focuses liquid strong emphasis applications. Studies combustion address flame parameters development laws. Ammonia serves an efficient storage medium. conversion involving will occur simultaneously both time space.

The safe use of hydrogen in commercial and industrial settings relies on highly sensitive fast-response sensors to effectively detect leaks. In this study, Pd/VO2 films were prepared by magnetron sputtering technology, the effects process parameters (including substrate temperature, oxygen partial pressure, power, time) crystallinity surface texture (morphology roughness) systematically studied, internal relationship between them was revealed. order further explore hydrogen-sensitive property material, response 1% H2 with different textures investigated. It is found that film a more prominent extending time based flattest exhibits an improved sensing 796%, 197 s, recovery 185 s. This result shows enhancement can improve performance material. study provides experimental basis theoretical guidance for improving gas-sensitive properties regulating materials through lays solid foundation design preparation high-performance sensors.
