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.
