抄録: The angular distribution of desorbing product N₂ was studied in N₂O decompositions on Rh(110) in the temperature range of 60–700 K. The N₂ desorption collimates along 62°–68° off normal toward either the [001] or [001¯] direction in a transient N₂O decomposition below ca. 470 K or in the steady-state N₂O+CO reaction above 540 K. In the steady-state reaction at the temperature from ca. 470 to 540 K, however, the collimation angle shifts from 62° to 45° with decreasing surface temperature. This angle shift is ascribed to the steric hindrance by coadsorbed CO because the N₂ collimation in transient N₂O decomposition at around 65° is recovered in the range of 380–500 K by an abrupt CO pressure drop followed by the decrease in CO coverage. N₂O is oriented along the [001] direction before dissociation. A scattering model of the nascent N₂ by adsorbed CO is proposed, yielding smaller collimation angles. ©2006 American Institute of Physics
