SENSING MATERIAL FOR GAS SENSOR, GAS SENSOR COMPRISING THE SAME, PREPARATION METHOD OF SENSING MATERIAL FOR GAS SENSOR, AND PREPARATION METHOD OF GAS SENSOR USING THE SENSING MATERIAL

摘要

The present invention suggests a sensing material for a gas sensor, the gas sensor comprising the same, a preparation method of the sensing material for the gas sensor, and a preparation method of the gas sensor using the sensing material. A sensation feature can be improved with the gas sensor including a Ni3V2O8 nano-structure with the sensing material. In accordance with the present invention, the sensing material including the Ni3V2O8 nano-structure is provided; the Ni3V2O8 nano-structure may have a network structure of nano-fibers to which nano-particles are attached; the average diameter of the nano-fiber may be 50nm to 5000nm; the Ni3V2O8 nano-structure may be porous; and the Ni3V2O8 nano-structure has a resistance value which can be changed in accordance with the concentration and existence of a specific gas.
