In this research, the effects of Al&S doped on the HCN interaction with beryllium oxide nanotube (BeONTs) are investigated by using density functional theory at the cam-B3LYP/6-31G (d) level of theory. Inspection of computational results reveals that the adsorption energies of all considered models are in range of −1.39 to −31.84 Kcal/mol and exothermic in view of thermodynamic approach. Due to...
