Sulfur hexafluoride (SF6) is extensively employed in gas-insulated switchgear (GIS) due to its exceptional insulating and arc-extinguishing properties. However, operational failures like arcing or overheating can lead the decomposition of SF6, releasing various gases such as H2S, SO2, SOF2, SO2F2, depending on fault type. The urgent need for efficient real-time sensors detect these highlighted. This study examines adsorption characteristics sensing materials based palladium phosphide (PdPS) composites with noble metals (Cu, Ag, Au) utilizing first-principles density functional theory simulations. analysis includes parameters distance, charge density, binding energy, transfer, molecular frontier orbitals, desorption kinetics. Optimal embedding sites were identified at TP positions PdPS surface, yielding energies −1.529 eV Cu, −0.987 −1.04 Au. Notably, while pristine exhibited unfavorable profiles, Cu-PdPS composite demonstrated significant capabilities −1.359 −1.245 −0.902 −0.806 SO2F2. Desorption kinetics reveal that Cu-modified system offers rapid times, notably 4.24 s SO2F2 room temperature, positioning it an excellent candidate ambient detection. Additionally, configuration shows enhanced versatility across varying temperatures, particularly excelling high-temperature conditions. findings underscore potential PdPS-based developing advanced sensors, paving way integrating low-power, high-sensitivity monitoring systems SF6 gas detection GIS applications, implications future research toward AI-driven models quantitative mixture analysis.

Although conventional heat-activated gas sensors effectively detect air pollutants such as highly toxic H2S and NO2, their high operating temperatures increase the risk of explosions in flammable environments, limiting applications. In this study, we report a novel composite material SnO2@Y2O3 synthesized using an electrospinning-solvothermal method. This is first demonstration sensing at room temperature heterostructures under low-power ultraviolet light. heterostructure has excellent performance, thanks to its rich adsorbed oxygen species [21.01%, significantly higher than pure SnO2 (11.55%)] enhanced interfacial charge transfer. The introduction Y element greatly reduces photogenerated electron-hole recombination efficiency UV Furthermore, sensor's response 10 ppm irradiation 318.3% that sensor. addition, sensor selectivity due interface potential barrier between two, least 6.8 times other interfering gases. DFT calculations further show adsorption energy on heterojunction (110) surface. electron transfer amount (0.385 e) 218.2% surface (0.121 e). work proposes new strategy for improving performance by introducing light excitation, providing low-temperature, safe, selective platform gases H2S.
