英文摘要	Joint density functional theory calculations have been performed to investigate the adsorption characteristics of H, O, OH and H2O on Fe(110) surface with and without the presence of electrolyte. Especially, the effect of applied electrode potential on the interaction between the adsorbates and substrate is discussed in this paper. The simulations results show that the presence of electrolyte has little effect on the surface energy and adsorption energy but apparently reduces the work function, and does not change the relative stabilities of the potential sites for four species. Under a positive potential, the adsorption becomes stronger and the species is attracted towards the surface, whereas under a negative potential, the adsorption is weaker and the species is pushed away from the surface. Potential dependent reorganization of water is observed and its spontaneous dissociation is not found over the entire applied potential range.
