Electroreduction of MoCl5 in Room Temperature Ionic Liquid at 150 oC

Abstract:

The electroreduction of MoCl5 was performed in the binary room temperature ionic liquid, lithium bis[(tri-fluoromethyl) sulfony]amide (LiTFSI) and cesium bis[(tri-fluoromethyl)sulfony]amide (CsTFSI) (eutectic point, 0.07: 0.93 in mole fraction; m.p., 112 oC) at 150 oC for the sake of electrodeposition of molybdenum. Analyses from cyclic voltammetry complemented by SEM-EDAX and XPS show that metallic molybdenum is electrodeposited on nickel substrate in the ionic liquid LiTFSI-CsTFSI containing MoCl5 at 150 oC. Quality of the deposits is improved by using galvanostatic electrolysis and pulsed current electrolysis
