通过高分辨率电子能量损失谱(HREELS)和角分辨紫外光电子能谱(AKUPS)等表面分析手段研究了CO在1ML Fe/Cu(110)表面的吸附性质.在该双金属表面存在两种吸附态——明显倾斜的低频吸附在和其C—O伸缩频率明显高于CO在Fe,甚至略高于在Cu单晶面的顶位吸附态.
The adsorption properties of CO on 1ML Fe / Cu (110) surface were investigated by means of surface analysis such as high resolution electron energy loss spectroscopy (HREELS) and angle-resolved ultraviolet photoemission spectroscopy (AKUPS) The state-obviously tilted low-frequency adsorption and its C-O stretching frequency were significantly higher than those of CO at Fe and slightly higher than the top sites of the Cu single crystal plane.
