A fundamental analysis of a metal reduction process is important for the development on metal plating, electric refining, and nanoparticle synthesis. Electrochemical and spectroelectrochemical methods have been applied for the mechanistic analysis of the noble metal nanoparticles formation as well as the actinide reduction. Ionic species and electron transfer reactions at the interface between aqueous and organic solutions were measured by charge transfer voltammetry at the liquid|liquid interface. Chemical status and redox characteristics of actinide ions in various solutions such as water, organic solutions, molten salts, highly concentrated electrolytes were studied by electrochemical methods combined with in-situ X-ray absorption spectroscopy.
