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.
