Magnesium Oxide Nanotube as Potential Sensor for Cl2 Detection

Adsorption of chlorine on the external surface of Mg15O15 nanotube was studied by using density functional calculations in terms of adsorption energy, energy gap changes, charge transfer, structural deformation, etc. It was found that the electronic properties of the Mg15O15 nanotube are very high sensitive to the presence of Cl-2 and the nanotube can significantly detect Cl-2 molecules. Also, the Cl-2 molecules have not a strong interaction with the nanotube to hinder the recovery of the nanotube. Based on calculated results, the Mg15O15 nanotube can be potential sensor for Cl-2 molecules detection.
