WebAbstract: Adsorption of CO on ideal and oxygen deficient Cu 1 /CeO 2 (110) surfaces was studied by density functional theory (DFT), and the adsorption characteristics of CO molecules at different sites on the modelled catalyst surface were calculated and analyzed. The results show that Cu-doping can significantly improve the adsorption performance … WebCO adsorbs weakly on the Au(111) surface, and is most stable in the bridge site, with an adsorption energy of 0.02 eV, in general agreement with previous studies. On Au(100) surface, each Au surface atom has eight nearest neighbours. Several structures with different adsorption geometries are identified and are shown in Figure 2.
