【Abstract】 Volatile organic amines are toxic and harmful, which pose a serious threat to the ecological environment and public safety. The rapid detection of organic amines is of great significance for environmental pollution prevention, food safety monitoring and even medical diagnosis. Based on the research progress of tin dioxide semiconductor materials in the detection of organic amine, the formation of heterojunctions between tin dioxide and metal oxides, metal sulfides, carbon materials and organic polymer reported recently, and the effects of heterojunctions on amine-gas sensing performance were summarized. The other materials possessing heterojunctions and their applications in amine-gas sensing fields were prospected.更多还原
