Trimethyl phosphate based neutral ligand room temperature ionic liquids for electrodeposition of rare earth elements
Abstract
In this communication, a new class of task-specific ionic liquids (ILs) with cationic rare earth elements (REEs) is reported. These novel ILs have a wide electrochemical window of about 6 V, enabling direct electrodeposition of REE metals at room temperature. The ILs were prepared by dissolving bis(trifluoromethane)sulfonimide (NTf2–) based rare earth salts (Ln(NTf2)3) (Ln:Lanthanide) in trimethyl phosphate (TMP) neutral ligand. Specifically, four REEs (Nd, Dy, Gd, and Pr) have been investigated in TMP based IL systems. All four metals were successfully deposited at room temperature. In conclusion, this demonstrates the applicability of the IL systems for electrodeposition of a wide range of REEs, which opens a new avenue of research for the quest to supplant high temperature molten salt systems for rare earth deposition.
