摘要：

The electrochemical deposition of magnesium from [Mg-2(mu-Cl)(3)center dot 6(OC4H8)](+) has been monitored in situ with X-ray absorption spectroscopy. The viability of the cell design was confirmed by a reversible shift in the X-ray absorption near-edge spectroscopy (XANES) of the Mg K-edge. In situ electrochemical XANES revealed the presence of an interfacial Mg intermediate below the equilibrium Mg/Mg2+ potential. A new method has been established to directly observe the complex electrochemical reduction process from Mg electrolytes. (C) 2012 Elsevier B.V. All rights reserved.
