SnO2-based semiconductor gas-sensing materials are regarded as some of the most crucial sensing materials, owing to their extremely high electron mobility, sensitivity, and excellent stability. To bridge gap between laboratory-scale SnO2 its industrial applications, low-cost high-efficiency requirements must be met. This implies need for simple synthesis techniques, reduced energy consumption, satisfactory performances. In this study, we utilized a surfactant-free method modify nanoparticles with PdPt noble metals, ensuring stable state material. Under synergistic catalytic effect Pd Pt, composite material (1.0 wt%-PdPt-SnO2) significantly enhanced response HCHO. modification decreased optimal working temperature low 180 °C achieve value (Ra/Rg = 8.2) showcased lower operating temperatures, higher better selectivity detect 10 ppm HCHO when compared pristine or single metal-decorated sensors. Stability tests verified that gas sensor signals based on PdPt-SnO2 exhibit good reliability. Furthermore, portable detector was designed practical such in newly purchased cushions, indicating potential industrialization beyond laboratory.

At atmospheric pressure, the main challenge in photocatalytic oxidation of CH4 to CH3OH is absorb and activate inert C─H bond while preventing excessive CH3OH. In this study, metal-supported ZnO nanoflowers (Ag-ZnO) are designed produce abundant active interfacial oxygen sites for at with a yield reaching 1300 µmol gcat -1 h-1 selectivity 94%. DFT calculation situ analysis show that addition Ag regulates electron state density band center O, which beneficial adsorption CH4, decreases dissociation energy barrier OL(Lattice oxygen) site. The further selective conversion ·CH3 involves two different pathways: one pathway consists by OL, other combination ·OH generated from dissolved O2 (0.28 mm) water. Notably, photochemical flow device, increased 5200 close 100%. This work offers valuable insights into reactive interfaces, morphological engineering, control intermediate evolution toward oxygenates pressure.

The detection of hydrogen sulfide (H2S) in exhaled breath at room temperature is essential for health monitoring and disease diagnosis. This study investigates a ZnO/Ti3C2TX nanocomposite synthesized by combining ZnO nanoparticles, prepared hydrothermal method, with Ti3C2TX MXene. Experimental results demonstrate that the sensors exhibit excellent H2S performance high sensitivity, rapid response time, robust recovery capability. Specifically, ZnO/Ti3C2TX-1.0 wt % sensor shows 85.116 5 ppm H2S, which 14-fold 35-fold greater than pure MXene, respectively. exhibits (50 s) time (115 100 ppb H2S. Additionally, it exceptional sensitivity to low concentrations, limit as 1 ppb. Based on sensing performance, oral gas demonstrates effectively differentiates levels healthy patient samples. These findings highlight potential temperature, offering new insights developing ultrasensitive biogas sensors.
