| Outline of Final Research Achievements |
The unique and exotic phenomena in electrochemical properties of two-dimensional (2D) materials was visualized by nanoelectrochemical imaging technique in this project. The investigated reactions were not only electrocatalytic reactions: hydrogen evolution reaction and oxygen reduction reaction, but also the redox activities via redox mediator and lithium-ion (de)intercalation process were examined. Further, various types of factors to introduce their high activities were successfully quantified by the technique such as edge-basal structures, number layers, wrinkle, chemical dopants. Their spatial resolution was improved with a 30 nm diameter pipette and optimized measurement control system. From those results, the intrinsic mechanism of their electrochemical properties in nanoscale will be unveiled.
