Preparation of magnesium thin film by non-aqueous electrolysis at room temperature

Abstract

The synthesis of a magnesium thin film by simple electrolysis was investigated in three non-aqueous electrolytes. Linear sweep voltammograms of magnesium on the copper electrode showed the possibility of electrodepositing metallic magnesium at room-temperature. Morphology of the magnesium thin film could be controlled by controlling the applied current. The metallic magnesium thin film could be easily and uniformly deposited on a copper electrode under galvanostatic conditions in THF solution of EtMgBr. The magnesium film formation was confirmed by X-ray diffractometry and scanning electron microscopy with energy-dispersive spectroscopy.
