Adsorption of N2O on pristine and oxygen vacancy defect ZnO and BeO nanotubes was studied at the B3LYP and M06-2X levels of theory. It was found that this molecule can be used to repair the oxygen vacancy defects of these tubes. Adsorption energies of the dissociation of N2O on the defective BeO and ZnO nanotubes were calculated to be about 786.2 and 506.1 kJ/mol at the B3LYP level of theory, respectively. Molecular adsorption is barrierless, while the dissociative adsorptions have to overcome a small activation energy.
