Electrochemical Phase Change of Iron Rusts by In-Situ X-ray Diffraction Technique

Abstract

In order to investigate the electrochemical cathodic reduction behavior of rusts, we propose the electrochemical cell and the optical conditions for in-situ X-ray diffraction technique. The electrochemical phase change of rust was able to be followed as a function of time. It was observed that β-FeOOH was reduced, and then spinel type iron oxide was formed.
