One-dimensional tight-binding model and the one-electron chemisorption theory are used to calculate the chemisorption energy of CO or O on NixCu1-x surface under the average T-matrix approximation. It is found that the chemisorption of CO and O on NixCu1-x are strengthened with the increase of bulk Ni concentration. The Cu segragation to the NiCu alloy surface may weaken the chemisorption.
