This study investigates the gas-sensing capabilities of heterostructure sensors based on hydrogen-terminated nanocrystalline diamond (H-NCD), molybdenum disulfide (MoS₂), and functionalized graphene oxide (SH-GO, GO) for detecting ethanol, ammonia (NH₃), nitrogen dioxide (NO₂) gases at 100 ppm concentrations. Sensors were tested two distinct temperatures: 125°C room temperature (22°C). Among sensors, SH-GO/H-NCD exhibited highest sensitivity to with a response 634% 22°C 554% 125°C. The Au NPs/H-NCD sensor showed second-best ethanol 587% For NH₃, demonstrated best value 76%, while temperature, it 41%. NO₂ sensing negative responses, exhibiting least degradation -47% -19% 22°C. results highlight those combining materials into heterostructures significantly enhances gas detection performance, even showing comparable responses commercial sensors.

The SnO2@Bi2O3 core-shell heterojunction structure was designed and synthesized via a hydrothermal method, the morphology of samples were characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM), photoelectron spectroscopy (XPS). Based on conclusions from XRD SEM, it can be observed that as temperature increases, content Bi2O3 coated surface SnO2 spheres gradually diameter nanoparticles also increases. At 160 °C, are fully with nanoparticles. This paper investigated gas-sensitive performance sensor towards ethanol gas. Gas sensitivity tests at optimal operating 300 °C showed composite prepared achieved response value 19.7 for 100 ppm ethanol. Additionally, exhibited excellent to ethanol, time only 4 s, well good repeatability. gas is attributed its p-n material properties. Its successful preparation contributes realization high-performance heterostructure sensors.
