| 摘 要： | 应用原子和表面簇合物相互作用的5-参数Morse势(简称5-MP)方法系统地研究了氧-铂台阶面体系.理论结果表明:在Pt(s)-n(111)×(100)]型台阶面上，氧原子吸附在台阶下的四重位，对应稳定吸附态β2；平台上靠近四重位的三重吸附态被湮灭，其它三重位对应吸附态β1；而且平台的长度对四重吸附态有影响.

| Abstract: | Oxygen adsorbed on Pt stepped surfaces has been studied by means of the 5-parameter morse potential(5-MP) of interaction between an adatom and metal surface cluster .The theoretical calculated results about O/Pt(s)-n(111)×(100)] systems draw some conclusions. The four-fold site behind a step that an oxygen atom binds in corresponds to the most stable state named β2-state. And the three-fold site near the four-fold site at a (111) terrace is annihilated, then the other three-fold sites correspond to adsorption states named β1-state. In addition the length of the (111) terrace has effect on the four-fold state. |
