Co（0001）表面氧物种及其与CO的作用
Surface Oxygen Species and the Interaction with CO on Co(000 1)
摘要
Abstract
The adsorption,activation of O2 molecule,as well as,the interaction with CO on the Co(0001)surface have been investi-gated with high-resolution electron energy loss spectroscopy (HREELS),low-electron energy diffraction (LEED),and Auger electron energy spectroscopy (AES).The results show that chemisorbed oxygen species and CoO are stable at room temperature (RT),with an energy peak loss at 69.9 meV.At higher O2 exposure,another energy peak loss at 56.6 meV emerges,which can be ascribed to subsurface oxygen species.The results turn out to be that this oxygen species is less stable towards annealing in vacuum and interacting with CO.The CO on surface could be replaced by oxygen at RT,on the contrary,the surface oxygen species removed by CO requires a higher temperature.关键词
