چکیده

Using the dispersion-corrected DFT calculations, different adsorption modes of formamide molecule are studied over the pristine and Al-doped boron nitride nanosheets (BNNS). It is found that the interaction between the Al atom and its neighboring N atoms in the Al-doped BNNS is very strong, which would hinder the dispersion and clustering of the Al atoms over the BNNS surface. Unlike the pristine nanosheet, the electronic properties of Al-doped BNNS are very sensitive to the formamide adsorption. The adsorption energies of formamide over the Al-doped sheet are in the range of -0.93 to -1.85 eV, which indicates the quite strong interaction of this molecule with the surface. Moreover, the dehydrogenation of formamide over the Al-doped BNNS is examined. According to our results, the N-H bond scission of formamide is more energetically favorable than the C-H one.
