The adsorption of trichloroethylene (C2HCl3) molecule on the surfaces of the beryllium oxide (BeO) nanotube was investigated by means of density functional theory. The results show that the adsorption of trichloroethylene on both (4,4) and (8,0) nanotubes are inn chemical adsorption range, and changes energy gap in the (4,4) nanotube are more significant.
