The current research aims to synthesize zinc oxide decorated with palladium nanoparticles and develop a stable sensor high sensitivity hydrogen gas dissolved in oil. ZnO nanorods (NR) were synthesized by hydrothermal method directly onto commercial board gold interdigital electrodes, followed functionalization Pd (NP) drop casting. SEM images show NRs an average diameter of ∼220 nm spherical NPs diameters 35-75 nm. Finally, the sensing properties examined immersing into insulating mineral oil closed system, where different H2 concentrations (from 0 up 500 ppm) injected headspace then oil, according Ostwald coefficient. All measurements carried out at room temperature. electrical characterization showed that our had good repeatability, stability, detect lower (less than 10 ppm). Additionally, nanoengineered porous layer PDMS was prepared over through spin coating heat treatment, reached ∼2.8 ppm gas. Our findings indicate methodology applied improves detection performance industrial applications its potential use for real-time monitoring.

Two-dimensional materials used for gas-sensing can be classified as donors or acceptors based on the different directions of electronic transfer. Meanwhile, external strain, by disrupting balance forces between electrons, significantly impacts electron transfer process material and gas molecules, thereby altering properties. In this paper, single-layer As6/Sb6 lateral heterojunctions (LHSs) with armchair zigzag (ZZ) interfaces have been constructed. The NO2 molecule NH3 are adsorbed these LHSs, making LHSs act acceptors, respectively. adsorption properties before after applying types strain calculated first principles. Notably, compressive exacerbates structural deformation all LHSs. addition, promotes charge sensing but hinders sensing. energy ZZ-LHSs compression largest, indicating great potential This work lays foundation designing predicting high gas-sensitivity materials.
