In this study, square-star-shaped leaf-like BiVO4 nanomaterials were successfully synthesized using a conventional hydrothermal method. The microstructure, elemental composition, and gas-sensing performance of the materials thoroughly investigated. Morphological analysis revealed that prepared at different reaction temperatures exhibited structures, with most regular dense structures formed 150 °C, exhibiting large specific surface area 2.84 m2/g. response gas sensors to target gases was evaluated, results showed sensor strong NH3. At optimal operating temperature 300 its sensitivity 5 ppm NH3 reached 13.3, time 28 s recovery 16 s. Moreover, excellent repeatability anti-interference performance. These findings indicate holds great potential in environmental monitoring industrial safety detection, offering new insights for development high-performance sensors.

Using density functional theory and the nonequilibrium Green function method, interaction between two-dimensional nitrogen-doped graphyne (N-GY) volatile organic compounds (ethanol, ethylene glycol, acetone, toluene) was investigated, potential application of N-GY for sensing biomarkers exhaled by human breath explored. The is a direct band gap semiconductor with width 0.408 eV. bottom conduction top valence are both located at Γ point. All target (VOCs) in physical adsorption states. In order to verify mechanism VOCs, Bader charge transfer, distance, work function, electron localization difference, energy structure, states were analyzed. At same time, I–V relationship VOCs molecules before after calculated using NEGF method. results show that 0.5 V bias voltage under armchair direction, can well distinguish four gas has highest sensitivity acetone 81%. Therefore, monolayer candidate material analyzing body as early screening diabetes.
