We study, for the first time, the adsorption and catalytic decomposition of N2O molecule over a fullerene-like boron nitride nanocage (B12N12) using density functional theory calculations. It is found that the electron donating property of the cage plays an important role in the adsorption and activation of N2O. By the incorporation of a carbon atom into B12N12 cluster, our results indicate that the adsorption of N2O over B11N12C or B12N11C is more stronger than over pristine B12N12. The decomposition of N2O into N2 and O species over the C-doped clusters is energetically more favorable than that on B12N12. Moreover, the C-doping plays an important role in reducing the activation barrier for the CO + O* reaction over B12N12 surface.
