摘要：

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 & LCIRC;C. 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.
