| Outline of Final Research Achievements |
For the purpose of in-situ experiment on lead negative electrode with high sensitivity of electrochemical (EC) reaction as well as with the atomic level observation, frequency modulation atomic force microscope (FM-AFM) was established with using EC system. First, as an introduction experiment, in order to design a new concept cantilever holder for EC-FM-AFM under the demanded dilute sulfuric acid environment, preliminary experiment to survey a necessary condition was carried out, then new cantilever holder which has solid reference electrode made by cadmium was manufactured. Secondly, a demonstration of EC-FM-AFM observation with using new cantilever holder was practically done, which has been regarded to be difficult under the dilute sulfuric acid environment. The effect of doping of the lignin into the electrolyte was not unfortunately confirmed even when the density of the dilute sulfuric acid was changed.
