Research Abstract

For the full understanding of electrochemical reactions, structural changes of adsorbed reactants as well as water molecules around the surface should be studied in a time-resolved manner. We have found that the laser-induced orientation change of water molecules in the electric double layers causes a sudden change in electrode potentials. The detailed analysis of the potential jump revealed that water molecules on a hydrophobic surface are more flexible than on a hydrophilic surface. Structured water layers on a hydrophobic surface is readily destroyed by the forced approach of hydrophilic cations than by hydrophobic cations.
