In this study, H₂ sensors were developed with Pd-doped porous WO₃ (Pd/WO₃) as the sensing material using different amounts (wt%) of Pd. Pd/WO₃ was synthesized using an in-situ high-temperature solvothermal method. The surface morphology and nanostructure of Pd/WO₃ were characterized through X-ray diffraction and high-resolution transmission electron microscopy. 1.0 wt% Pd/WO₃ exhibited the highest hydrogen-sensing ability compared to pure WO₃ and 0.5 wt% and 1.5 wt% Pd/WO₃ at 100 ℃. The Pd/WO₃-based gas sensor demonstrated promising H₂-sensing characteristics, such as high selectivity and good repeatability. Therefore, this sensor is an excellent candidate for use in applications that require high-performance low-temperature H₂ sensing.
