Outline of Final Research Achievements

We reveal the structure and the role of interfacial water by the experimental simulation of the electrical double layer. By the optimization of adsorption protocol and annealing temperature for the coadsorbed layer of water and alkali metal on Ag(100), the modeling under ultra-high vacuum can simulate the electrode interface that the hydrated alkali metal cations are located on the surface.
In-situ X-ray diffraction reveals the orientation change of interfacial water on the graphene electrode and the dehydration process during metal deposition. The water bi-layer structure on the graphene electrode is formed and the layer spacing of bi-layer depends on the electrode potential.
