摘要：
Inclined N-2 desorption was examined in the course of a catalyzed N2O + D-2 (or CO) reaction on Pd(110) by angle-resolved mass spectroscopy combined with cross-correlation time-of-flight techniques. N-2 desorption collimated at around 45 off the normal toward the [001] direction in the temperature range of 400-800 K. Its collimation angle and kinetic energy were insensitive to both the surface temperature and surface conditions throughout the kinetic transition. It is proposed that this peculiar N-2 desorption is induced by the decomposition of N2O oriented along the [001] direction.
