| Outline of Final Research Achievements |
Reactions at metal/solution interfaces accompanying solution and precipitation are key in corrosion of metals and electrochemical reactions at electrodes of batteries. However, in situ observation of these reactions has been experimentally difficult, because the interface morphology changes as the progress of reactions.
In this study, we have developed a technique to in situ observe and visualize the concentrations and chemical states of species in solution near the interface, by combination of synchrotron radiation and x-ray absorption spectroscopy. We have applied this technique to pitting reactions of stainless steel and revealed its mechanism.
