Detection of trimethylamine (TMA) gas using mixed shape cobalt doped ZnO nanostructure

High-Performance Trimethylamine Sensor Based on an Imine Covalent Organic Framework

“…TMA is a colorless, flammable, and toxic volatile organic compound . Inhalation of TMA can cause various health problems, such as eye irritation, nausea, headache, difficulty breathing, pulmonary edema, and damage to the upper respiratory tract. , The American Conference of Governmental Industrial Hygienists has recommended long-term and short-term air exposure limits for TMA of 5 and 15 ppm, respectively . Humans may experience severe physical and psychological distress after prolonged exposure to TMA gas due to its widespread use in agriculture and industry. − In addition, TMA also poses a serious risk to human safety because it burns or explodes violently when exposed to open flames or high temperatures and produces harmful fumes from thermal decomposition .…”

“…Adsorption and desorption were controlled within a cycle time of 17 s. As a result, most current sensing materials for TMA detection consist of metal oxides. Most research has been conducted at high temperatures. ,− However, very few studies have been conducted at room temperature (RT), − which limits their use to only a few applications for portable and RT gas sensors. New sensing materials are being sought to develop highly sensitive semiconductor gas sensors at RT for fast, reliable, nondestructive, and real-time detection of TMA.…”
