Toxic and harmful gases, particularly volatile organic compounds like triethylamine, pose significant risks to human health the environment. As a result, metal oxide semiconductor (MOS) sensors have been widely utilized in various fields, including medical diagnostics, environmental monitoring, food processing, chemical production. Extensive research has conducted worldwide enhance gas-sensing performance of MOS materials. However, traditional materials suffer from limitations such as small specific surface area low density active sites, leading poor gas sensing properties—characterized by sensitivity selectivity, high detection limits operating temperatures, well long response recovery times. To address these challenges triethylamine detection, this paper reviews synthesis nano-microspheres, porous micro-octahedra, hollow prism-like nanoflowers via solution methods. The materials, ZnO In2O3, can be significantly enhanced through nano-morphology control, electronic band engineering, noble loading. Additionally, strategies, elemental doping, oxygen vacancy modulation, structural morphology optimization, employed achieve ultra-high detection. This review further explores underlying mechanisms responsible for improved sensitivity. Finally, perspectives on future directions are provided.

Carbon monoxide (CO) is infamous for its hazardous effects, mainly because it displaces oxygen in the bloodstream. Its danger amplified by odorless and colorless nature, making difficult to detect. Exposure even low concentrations of CO (≤50 ppm) considered harmful human health. Common sources CO, such as fossil fuel-powered vehicles machinery, primarily operate under harsh high-temperature conditions. Currently, available low-ppm sensors struggle these environments typical emitters, highlighting urgent need advanced capable reliable operation In this study, nanocrystalline mesoporous icosahedral boron subphosphide synthesized via a solid-state technique evaluated sensing capabilities. The material exhibits selective detection ppm at temperatures exceeding 500 °C, demonstrating significant response ∼4 toward 50 600 °C. Electronic structural analyses attribute subphosphide's chemiresistive behavior electron-deficient which crucial effective interaction. Additionally, sensitivity can be modulated external magnetic fields, underscoring potential adaptable applications. This work introduces promising candidate conditions provides fundamental insights into mechanism driven intrinsic electron deficiency. findings offer pathway development reliably detecting where precise monitoring critical public health safety.
