摘要
用高分辨电子能量损失谱研究CO在有序表面合金Cu{001}c(2×2)-Pd上的吸附位置,在240K,CO仅直立地吸附在Pd原子的顶位;在135K,低覆盖度时,CO仅直立地吸附于Pd原子顶住,覆盖度增加后,CO同时直立地也吸附于Pd和Cu原子的顶位。
The site of CO adsorbed on Cu {00l}c(2×2)-Pd ordered surface alloy has been studies using high resolution electron energy loss spectroscopy (HREELS). CO molecules are bonded vertically only on top sites of Pd atoms at 240K. At 135K, CO molecules are bonded vertically on top position of Pd atoms also under low coverage, and CO adsorbed both on top site of Pd and Cu atoms under high coverage.
