摘要

Fe_2O_3 particles were successfully synthesized by hydrothermal method. The morphology and gas sensing properties were investigated. The results shows that the diameter of the minor axis and major axis of ellipse-like Fe_2O_3 is about 800 nm and 500 nm, respectively. The sensor based on Fe_2O_3 particles exhibits an good response of about 48.2 to 1000 ppm triethylamine at optimum operating temperature of 400oC. The response time is 21 s, showing fast response to triethylamine.
