Abstract:

Electrical sensitivity of a beryllium oxide nanotube (BeONT) was examined toward aniline (C6H5 NH2) molecule by using Density Functional Theory (DFT) calculations at the B3LYP/6-31G (d) level, and it was found that the adsorption energy (Ead) of aniline on the pristine nanotubes is about -19.06kcal/mol. However, when nanotube has been doped by P and S atoms, the adsorption energy of aniline molecule was decreased. The calculation showed that when the nanotube is doped by S, The adsorption energy is about -8.61kcal/mol and also the amount of HOMO/LUMO energy gap (Eg) will reduce significantly. As a conclusion, Beryllium oxide nanotube is a suitable adsorbent for aniline and can be used in different processes of aniline. It seems that nanotube (BeONT) is an appropriate semiconductor after being doped. The doped BeONT in the presence of aniline generates an electrical signal directly and therefore can be potentially used for aniline sensors.

Water adsorption and dissociation on BeO (001) and (100) surfaces

Plateaus in water adsorption isotherms on hydroxylated BeO surfaces suggest significant differences between the hydroxylated (100) and (001) surface structures and reactivities. Density functional theory structures and energies clarify these differences. Using relaxed surface energies, a Wulff construction yields a prism crystal shape exposing long (100) sides and much smaller (001) faces. This...

Gas molecule adsorption in carbon nanotubes and nanotube bundles

We studied various gas molecules (NO2, O2, NH3, N2, CO2, CH4, H2O, H2, Ar) on single-walled carbon nanotubes (SWNTs) and bundles using first principles methods. The equilibrium position, adsorption energy, charge transfer, and electronic band structures are obtained for different kinds of SWNTs. Most molecules adsorb weakly on SWNTs and can be either charge donors or acceptors to the nanotubes....
