| Research Abstract |
In situ electrochemical X-ray photoelectron spectroscopy (XPS) apparatus, which allows XPS at solid/liquid interface under potential control, was constructed utilizing an environment-cell with an ultra-thin membrane, which serves as a separator between vacuum and a solution, window for X-ray and photoelectron, and electrode. Its operation was demonstrated for potential induced oxide growth at the membrane/water interface and electrochemical deposition of metal on the membrane from the electrolyte solution.
