چکیده انگلیسی:
This paper investigated boron nitride nanocage performance as an adsorbent and sensing material for removal and detection of trinitroanisole by density functional theory. The calculated adsorption energies, Gibbs free energy changes (ΔGad), adsorption enthalpy changes (ΔHad) and thermodynamic equilibrium constants (Kth) revealed the adsorption process is experimentally feasible, spontaneous, exothermic and Irreversible. The highly negative adsorption energy values and bond lengths between B12N12 and trinitroanisole indicated the interaction between the adsorbate and the adsorbent is a chemisorption process. The N-O and C-N bond lengths and the density values showed that trinitroanisole complexes with boron nitride cage have higher explosive velocity and detonation pressure than the pure trinitroanisole without B12N12. The frontier molecular orbital parameters such as band gap, chemical hardness, electrophilicity, chemical potential and charge capacity were also studied and the findings proved B12N12 is an excellent sensing material for fabricating novel electrochemical and thermal sensors for detection of trinitroanisole.
