Moisture-resistant high-selective-response triethylamine gas-sensitive material constructed based on bimetal MOF (Metal Organic Framework) route as well as preparation method and application thereof

The invention belongs to the technical field of semiconductor oxide functional materials and chemical sensors, and discloses a humidity-resistant high-selective-response triethylamine gas-sensitive material constructed based on a bimetal MOF (Metal Organic Framework) route as well as a preparation method and application of the humidity-resistant high-selective-response triethylamine gas-sensitive material. The preparation method comprises the following steps: preparing a Sn/Zn bimetal MOF precursor, and calcining in a muffle furnace in an air atmosphere to obtain the humidity-resistant high-selective-response triethylamine gas-sensitive material. The gas-sensitive material can be made into a sensor with an indirectly heated structure for actual determination of triethylamine. At the working temperature of 270 DEG C, the gas-sensitive material disclosed by the invention has an excellent selective response characteristic on triethylamine. Meanwhile, the humidity-resistant high-selective-response triethylamine g
