CO, O and K coadsorption on Cu(lll) at oom temperature was investigated using high resolution electron energy loss spectroscopy (HREELS). The experimental results show that CO can adsorb on Cu(lll) surface precovered with K at room temperature and coadsorption of CO and K produce the K-O complexes. The K-O complexes can form only from the depolarized K at higher K coverage (θk>0.04).
