Abstract
When temperature of Pd(110) is raised in a flow of NO + H2, N2, N2O and NO are simultaneously desorbed at ca. 490–495 K and the catalytic reaction of NO + H2 → 1/2 N2 + H2O is followed at about 500 K. If 14NO is adsorbed on a 15N/Pd(110) surface, 14N15N and 15NO are simultaneously desorbed at 490–495 K. Interestingly, the N2 desorbed at ca. 490 K takes on a very sharp off-normal spatial distribution expressed by cos46(θ + 38°) towards to the 〈001〉 axis. The result strongly suggests that the N2 is formed by a surface reaction with anisotropic collision of moved N(a) with adsorbed NO(a). In contrast, the N2 formed by the catalytic reaction of NO + H2 → 1/2 N2 + H2O takes on a cos θ distribution, indicating thermal equilibrium is attained.
