The study of aluminium deposition from tetrahydrofuran solutions of AlCl3–LiAlH4 using microelectrodes. Part 1.—1:1 AlCl3–LiA1H4

Abstract

The electrodeposition of aluminium from 0.5 mol dm^–3 AlCl₃–0.5 mol dm^–3 LiAlH₄ in THF has been investigated using potential sweep and step techniques at microelectrodes. In the potential range usually employed, only one of several Al^III species is reduced to the metal, but the kinetics of this Al^III/Al couple are rapid. The influence of cathode material on the nucleation and growth of aluminium and of temperature on nucleation, the equilibrium between the complexes in solution and the kinetics of electron transfer are discussed.
