Abstract

Aluminum nitride and boron nitride nanocages have recently been discovered. The properties of these compounds vary according to their size. In this paper, we study the adsorption of MELs on aluminum nitride and boron nitride nanocages in the solution phase using density functional theory. The results of adsorption energies indicate that during the adsorption on aluminum nanocages, ether oxygen atoms show stronger adsorption, while adsorption is stronger on boron nitride nanocage from the hydroxyl group oxygen. The results of thermodynamic calculations indicate that all adsorption positions of aluminum nitride are thermodynamically favorable. However, in the case of boron nitride, some positions are thermodynamically unfavorable. In terms of recovery time, borne nitride is not a good adsorbent because of very small recovery time. The aluminum nitride may be able to behave as a suitable sensor for the MELs in the solution phase. Nevertheless, boron nitride does not have this capability, since it does not significantly change the number of conducting electrons.
