The Adsorption Behavior of Gas Molecules on Mn/N- and Mn-Doped Graphene.

ABSTRACT: By using density functional theory (DFT), the adsorption behavior of gas molecules on defective graphene doped with manganese and nitrogen were investigated. The geometric structure, electronic structure, and magnetic properties of two substrates were calculated and the sensing mechanism was also analyzed. The results indicate that the MnSV-GP and MnN₃-GP have stronger structural stability, in which Mn atoms and their coordination atoms will become the adsorption point for five gas molecules (CH₂O, CO, N₂O, SO₂, and NH₃), respectively. Moreover, at room temperature (298 K), the recovery time of the MnSV-GP sensor for N₂O gas molecules is approximately 1.1 s. Therefore, it can be concluded that the MnSV-GP matrix as a magneti
