Abstract

Demand for simple and effective gas sensing sensors is growing rapidly due to the growing threat of triethylamine (TEA). Semiconductor tin oxide (SnO2) is one of the most widely used sensing materials for metal oxide gas sensors. In recent years, a lot of binary ternary compound researches have been carried out. In this paper, five different SnO2 samples were synthesized by simple synthesis method to understand the internal relationship and obtain different gas sensing characteristics. Based on the low temperature nitrogen adsorption tests and the atomic arrangement model, it can be inferred that different exposed surfaces play a key role in TEA sensing properties. In addition, the TEA sensing activity relationship of SnO2 exposed crystal faces is proposed as listed: (200) > (101) > (110).
