CO adsorption in nitrogen-doped single-layered graphene quantum dots: a spectroscopic investigation.

In this work, we investigate the adsorption process of CO in graphene quantum dots from the electronic structure and spectroscopic properties point of view. We discuss how a specific doping scheme could be employed to further enhance the adsorbing properties of the quantum dots. This is evaluated by considering the depth of the potential well, the spectroscopic constants, and the lifetime of the compound.
