The presence of ammonia in exhaled human breath serves as a crucial biomarker for renal diseases. This paper presents highly sensitive sensor operable at room temperature, utilizing Ti/Zr dual metal MOF its core component, synthesized through straightforward solvothermal reaction approach. Ti/Zr-MOF demonstrates excellent responsiveness to gas, with detection limit remarkable sensitivity, reaching low 2 ppm. Notably, the exhibits practical insensitivity similar concentrations other major...

Ethylene glycol is odorless and harmful to humans. Each year, a large number of fatal cases are caused by ethylene poisoning. Therefore, rapid identification crucial. In this study, clay-like Ti3C2Tx MXene exhibits larger interlayer spacing compared accordion-like MXene, which enhances the gas diffusion channels. Nitrogen doping can increase active sites MXene. The introduction nitrogen-doped carbon nanotubes into N-Ti3C2Tx was carried out enhance selectivity towards glycol, leading...
