Gas detection material with high sensitivity and selectivity for methyl benzene method for preparing the same and gas sensor comprising the gas detection material

摘要

The present invention relates to a gas sensor for detecting methylbenzene, a method for producing the gas sensor, and a gas sensor including the gas sensor. More particularly, the present invention relates to a gas sensor comprising methylbenzene containing a nanocomposite of Cr ₂ O ₃ and ZnCr ₂ O ₄ The gas sensing material for detection according to claim ₁ , wherein the atomic ratio of Cr in the Cr ₂ O ₃ and ZnCr ₂ O ₄ nanocomposites is 67.0 atomic% to 90.0 atomic% based on the sum of Cr atomic content and Zn atomic content, And a gas sensor including the gas sensitive material. According to the present invention, it is possible to provide a gas sensitive material having a high selectivity for methylbenzene versus other gases and a high detection sensitivity for methylbenzene, and also can easily control the composition of the gas sensitive material, It is possible to provide a method for producing a gas sensitive substance which can be synthesized.
