Zinc oxide nanoparticles (ZnO NPs) with varying levels of nitrogen (N) doping were synthesized using a straightforward sol–gel approach. The morphology and microstructure the N-doped ZnO NPs examined through techniques such as SEM, XRD, photoluminescence, Raman spectroscopy. characterization revealed visible changes in resulting from incorporation into lattice. These used fabrication conductometric gas sensors designed to operate at room temperature (RT) for detecting low concentrations NO2 air, under LED UV-Vis irradiation (λ = 400 nm). influence on sensor performance was systematically studied. findings indicate that N-doping effectively enhances ZnO-based sensors’ ability detect RT, achieving notable response (S R/R0) approximately 18 when exposed 5 ppm NO2. improvements gas-sensing capabilities are attributed reduction particle size narrowing optical band gap.

N-butanol is well known to be a flammable and harmful liquid that potential threat human health property. Therefore, it important monitor the concentration of n-butanol in surroundings. The need for highly efficient toxic gas detection urgent has been driving research on sensors practical applications. Molybdenum disulfide (MoS2) attracting significant interest at room temperature. Herein, we report biofunctionalized magnetic nanoparticles incorporated MoS2 sensing n-butanol. biosynthesized magnetite (CT-Fe3O4) were synthesized by addition Cinnamomum Tamala (CT) leaf extract, subsequently, nanocomposite was using hydrothermal method. Highly sensitive based MoS2-CT-Fe3O4 fabricated tested different concentrations nanocomposites showed good performance ( $$\Delta$$ R/Rair %) 72% towards 20 ppm n-butanol, indicating use

Gallium-doped zinc oxide (GZO) has demonstrated significant potential in gas-sensing applications due to its enhanced electrical and chemical properties. This study focuses on the synthesis, characterization, performance of GZO nanoparticles (NPs), specifically targeting CO₂ detection, which is crucial for environmental monitoring industrial safety. The samples were synthesized using a sol–gel method, their crystal structure was determined through X-ray diffraction (XRD), confirming successful incorporation gallium into ZnO lattice. photoelectron spectroscopy (XPS) employed analyze samples' elemental composition state, revealing presence Ga matrix providing insights doping effects. Transmission electron microscopy (TEM) combined with energy-dispersive (EDS) used confirm purity distribution samples, ensuring homogeneity doping. In-situ TEM measurements also conducted one three smallest size. experiment involved exposing sample argon (Ar) as reference gas carbon dioxide (CO₂) target evaluate sensor's response under real-time conditions. in-situ provided nanoscale observation changes parameters, particularly d-spacing, exhibited alterations exceeding 3.2% when exposed Ar gases. Furthermore, paramagnetic resonance (EPR) optical joint density states (OJDS) analyses performed examine defects comprehensively understand electronic within sample, respectively.
