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.
