Abstract
The electrochemistry of Te(IV) chloride in basic aluminum chloride‐1‐methyl‐3‐ethylimidazolium chloride molten salt was investigated at a glassy carbon electrode at 30°C. Absorption spectroscopy and titration experiments suggest that tellurium(IV) chloride is complexed as in these melts. can be reduced to elemental tellurium via a four‐electron process. The nucleation process for the electrodeposition of Te from reduction of exhibits characteristics indicative of kinetic control. Elemental Te can be further reduced to a Te(‐II) species which undergoes a reaction with Te(IV) to form Te. Elemental Te can also be electrodeposited from oxidation of Te(‐II). This process proceeds via 3D progressive nucleation with diffusion‐controlled growth. The average Stokes‐Einstein products for and Te(‐II) species are and , respectively.
