Sensing materials for gas sensor method for fabricating the sensing materials gas sensor including the sensing materials and method for fabricating the gas sensor

摘要

The present invention relates to a sensing material for a gas sensor including carbon nanotubes to which Lanthanum Fluoride (LaF ₃ ) nanoparticles are fixed, a method for manufacturing the same, and a gas sensor including the sensing material and a method for manufacturing the same . According to the present invention, by using the sensing material, it is possible to provide a gas sensor having excellent sensitivity and selectivity to F ₂ gas without an electrolyte. In addition, the gas sensor according to the present invention can measure the concentration of F ₂ gas and can operate at room temperature without using a heater, so that power consumption is minimized, and the gas sensor can be miniaturized and used for portable purposes.
