چکیده انگلیسی
The angular distribution of desorbing N2 was studied in the decomposition of N2O(a) on Rh(1Â 0Â 0) at 60-140Â K by means of angle-resolved temperature-programmed desorption. N2 desorption shows two peaks at around 80Â K and 110Â K. At low N2O coverage, the former collimates far from the surface normal toward the [0Â 0Â 1] direction, whereas at high coverage, the desorption sharply collimates along the surface normal. The adsorption form of N2O and its dissociation were also examined by DFT-GGA calculations. Dissociating N2O is proposed to be lying along the [0Â 0Â 1] direction at low coverage and to change to an upright form bonding through the terminal oxygen at high coverage.
