Abstract:

The adsorption behavior and related electronic properties of NH3 on perfect and defective boron nanotubes were investigated via density functional theory. The results show that for α-type boron nanotubes, NH3 is more likely to be adsorbed at the top position with the coordination number of 6 under different diametral and chiral conditions. The electronic structure calculation results show that the strong interaction between N and B atoms is the dominant reason for the stably adsorption of NH3 on the surface of boron nanotubes. It indicates that boron nanotubes are one of the potential NH3 gas sensitive materials.
