The electrodeposition of aluminium from five solutions in THF of AlCl3-LiAlH4 has been investigated using potential sweep and step techniques at Au microelectrodes.The ratios of AlCl3 to LiAlH4 range from 5:1 to 1:5 (total Al concentration always 1 mol dm-3).The nucleation overpotential, the exchange-current density and the maximum rate of Al deposition all depend on the solution composition and in extreme compositions the electroactive species can be different.A 1:1 solution appears to be a good choice for electroplating aluminium.The nucleation and growth of Al on Au from a 1:2 solution of AlCl3-LiAlH4 in THF has been studied in more detail.
