用ＨＲＥＥＬＳ，ＡＥＳ，ＬＥＥＤ 和ＴＤＳ考察了氮在含氧Ｍｏ（１００） 上的吸附和热脱附．１２０ Ｋ 下氮在含氧Ｍｏ（１００）上吸附时存在着Ｎ—Ｎ 伸缩振动频率２ １５０ 和１ ６００ ｃｍ －１ ， 分别对应于线式（γ态） 和侧位（α态） 两种分子吸附态．升温引起γ态氮的脱附和α态氮的解离． 其中γ态氮的脱附峰温位于１５５ Ｋ， 遵循一级脱附动力学； 由α态解离生成的Ｎ 原子占据Ｍｏ（１００） 的四重空位（ 即β态） ， 并在高于１１５０ Ｋ 的温度重新化合形成氮而脱附．１２０ Ｋ时，氮的吸附是无序的； 吸附了氮的表面经１ １００ Ｋ退火后生成了有序的ｃ（２×２）Ｎ表面结构．
Adsorption and thermal desorption of nitrogen on oxygenated Mo (100) were investigated using HREELS, AES, LEED and TDS. At 120 K, N-N stretching vibration frequencies of 2 150 and 1 600 cm -1 exist at the adsorption of nitrogen on oxygen-containing Mo (100), which correspond to the linear (γ-state) and lateral (α-state) Adsorption state. Temperature rise causes the desorption of γ-state nitrogen and the dissociation of α-state nitrogen. Among them, the peak temperature of desorption of γ-nitrogen is located at 155 K, which follows the first-order desorption kinetics. The N atom dissociated by α-state occupies the quaternary vacancy (β state) of Mo (100) The temperature of K is recombined to form nitrogen and desorbed. The adsorption of nitrogen is disorder at 120 K, and the surface of adsorbed nitrogen is annealed at 1 100 K to form an ordered c (2 × 2) N surface structure.
