Adsorption of nitrogen dioxide on C30B15N15 heterofullerene: AIM and NBO study via DFT

Adsorption of nitrogen dioxide on the exterior surface of C30B15N15 through B atom of adsorbent is studied using the DFT-B3LYP/6-31G* level. Independent to the orientation, the NO2 molecule presents strong chemisorption with large charge transfer from C30B15N15 to adsorbed gas. NBO (natural electron configuration of adsorbing B atom), AIM analysis and spin density distributions indicate that the chemisorption of NO2 on the C30B15N15 in all studied complexes are covalent in nature.
