Free energy of proton transfer at the water-TiO2 interface from ab initio deep potential molecular dynamics

This study found that water on the anatase (101) surface of TiO2 exists in a dynamic equilibrium of both molecular and dissociated forms, with the molecular form being more stable. A small fraction (5.6%) of water dissociates, forming short-lived hydroxyl groups, through a concerted proton transfer mechanism involving a mediating water molecule.

On the importance of the electric double layer structure in aqueous electrocatalysis

This study uses molecular simulations and experiments to explain the two peaks in the capacitance of an electrode-electrolyte interface, revealing that they originate from ion adsorption and structural changes in the water layer near the electrode. It also shows that modifying the water layer structure using crown ethers can alter the electric field and thus influence CO2 reduction reaction activity.
