Temperature Dependence of Sensors Based on Silver-Decorated Nitrogen-Doped Multiwalled Carbon Nanotubes

Adsorption energy () of different molecules interacting with (a) (5,5)-single walled carbon nanotubes doped with nitrogen (note that all molecules exhibit a poor interaction with the nanotube surface, thus suggesting a physisorption), (b) Ag(111) surface, showing large values of ; these results suggest that, in this case, chemisorption may be the main adsorption mechanism. Note that negative values of are associated with stable configurations.
