<p>A gas sensor capable of selectively sensing volatile basic nitrogen gas, such as trimethylamine, and a manufacturing method thereof are provided. According to the present invention, the gas sensor has a gas sensing layer formed of molybdenum (MoO_3) powders by a thermal cracking process. According to the present invention, the method for manufacturing the gas sensor is as follows. Molybdenum powders are formed by a thermal cracking process. The molybdenum powders are produced into the thin film structure, and the thin film structure forms a gas sensing layer. The gas sensor has a structure effective in diffusion of gas by easily controlling a fine structure by the thermal cracking method and can remarkably improve selective sensitivity to the trimethylamine gas by remarkably improving sensitivity of gas by blocking secondary particles from being increased.</p> |
