The development of reliable, highly sensitive hydrogen sensors is crucial for the safe implementation hydrogen-based energy systems. This paper proposes a novel way to enhance performance through integrating Pd-SnO2 nanofilms on substrate with silicon nanowires (SiNWs). samples were fabricated via simple and cost-effective process, mainly consisting metal-assisted chemical etching (MaCE) electron beam evaporation. Structural morphological characterizations conducted using scanning microscopy (SEM) X-ray photoelectron spectroscopy (XPS). experimental results showed that, compared those without SiNW structure or decorative Pd nanoparticles, Pd-decorated SnO2 nanofilm integrated substrates exhibited significantly improved sensing performance, achieving response time 9 s at 300 °C 1.5% H2 detection limit 1 ppm. enhanced can be primarily attributed large surface area provided by SiNWs, efficient spillover effect facilitated abundant oxygen vacancies present nanofilm, as well Schottky barrier formed heterojunction interface between SnO2. study demonstrates promising approach developing high-performance characterized ultrafast times ultralow limits.

Abstract Methane (CH 4 ) serves as a commonly utilized fuel gas in various industrial and everyday settings. Given its flammable, explosive, greenhouse nature, the real‐time monitoring of concentration air holds vital importance across practical applications. The tetrahedral structure methane molecules features high bond energies, posing significant challenge for chemical detection over metal oxide‐sensitive layers. In this research, multicomponent assembly method is used to synthesize ordered mesoporous tin oxide (SnO 2 with uniform large mesopores (≈ 10 nm) pore wall functionalized Pd x Pt nanoalloys 2.5 nm), due unusual C–H activation capabilities semiconducting properties SnO , obtained Pt@m‐SnO fabricate sensors which showcases wide applicability range detecting concentrations ranging from 50 20 000 ppm at 400 °C, it yields substantial CH response 9.19 (1000 ppm) an ultralow limit value 175.9 ppb. Furthermore, sensor successfully incorporated into portable device, evidencing capability accurate real‐world scenarios.

Developing cost-effective NO2 sensors with ppb-level limit of detection (LOD) is crucial for effectively monitoring this widespread toxic gas. SnO2, a promising candidate, suffers from limitations including poor selectivity, high operating temperature, and sensitivity to moisture. To address these challenges, we synthesized high-performance Sb-doped SnO2 via hydrothermal method. All products exhibit rutile tetragonal crystalline structures consist fine nanoparticles, primarily in the several-nanometer range. It found that dopant activation lattice dependent on both temperature doping concentration minimum resistivity achieved at optimal annealing temperature. For sensor fabrication, an condition 300 °C ambient air 2 h was chosen. demonstrated prominent selectivity toward NO2. The response follows volcano-shaped curve, 1.0 2.0 atom % exhibiting highest responses room (∼25 °C). This peak shifts 0.1 75 °C. achieving progressively decreases increasing Sb doping, while moisture resistance also improves. SnO2:0.1%Sb demonstrates most impressive overall performance, higher stability against variation. boasts ultrahigh 2.65 × 104, rapid response/recovery times 153 s/11 s 1 ppm °C, LOD down 20 ppb. Density functional theory calculations suggest moderate level leads stronger adsorption, explaining observed performance concentrations.
