Ti3C2Tx MXene, a two-dimensional (2D) materials with ultra-thin structure, has been fabricated as gas sensors working at room temperature with various thickness. In this work, two critical features towards reducing gases (NH3 and CO) and oxidizing gas (NO2) are characterized in a dynamic model. On one hand, the thickness of the Ti3C2Tx MXene material affects the sensing performance that the response to gases is declined with the increasing thickness of the Ti3C2Tx MXene. On the other hand, the Ti3C2Tx MXene based gas sensor is not appropriate for strong and moderate oxidizing gas (NO2) compared with the reducing gases (NH3 and CO). These two rules are demonstrated, and could be considered with priority both in the future researches and practical applications.
