用高分辨电子能量损失谱、愤怒电子能谱和原子分辨扫描隧道显微镜成像研究了由于吸附在Au/Pd(111)双金属表面不同双功能位而引起的CO-金属相互作用的修饰。通过比较系统变化的表面形貌和局部成分，我们可以区分CO在Pd(111)位、Au岛边缘位和PdAu混合表面位上的吸附，从而在局部结构和局部化学行为之间建立了明确的关联。(C)1997年爱思唯尔科学公司。
The modification in CO-metal interaction due to adsorption on different bifunctional sites on a Au/Pd(111) bimetallic surface was identified by high resolution electron energy loss spectroscopy, Anger electron spectroscopy and atomic resolution scanning tunnelling microscopy imaging. By comparison of surfaces with systematically varied morphology and local composition we could distinguish between CO adsorption on Pd(111) sites, Au island edge sites and mixed PdAu surface sites and this way establish a clear correlation between local structure and local chemical behavior.
