Abstract:

Triethylamine is a widely used volatile organic compound with toxic and side effects on human body,which needs long-term and effective monitoring.The development of stable,safe and reliable triethylamine gas sensor to realize the real-time detection of triethylamine gas concentration in the environment is very important for the safe storage,transportation and use of triethylamine.Metal oxide semiconductor based gas sensor has the advantages of simple preparation,low price and high response value.It plays an irreplaceable role in the detection of triethylamine gas.The latest research progress of triethylamine sensor based on metal oxide semiconductor was introduced.The recent research results on the preparation and properties of metal oxide semiconductor based triethylamine gas sensing materials,including doping,heterojunction,organic metal skele-ton and redox grapheme were reviewed.The mechanism of gas sensing properties of metal oxide semiconductor matrix compo-sites to triethylamine was discussed.And the future research direction of metal oxide-based triethylamine gassensitive materi-als was prospected.

Key words: metal oxide semiconductor, triethylamine, nanomaterials, gas sensors
