Outline of Final Research Achievements

It is believed that aluminum cannot be electrodeposited from aqueous solutions. In this study we sought a possible way to explode the established theory. Electrodeposition experiments were conducted under various conditions. Deposits containing Al and Ni could be obtained from aqueous solutions by adding an organic acid. Although metallic nickel was identified in the deposits, metallic aluminum or aluminum compounds were not found. Further investigation is required to determine how aluminum exists in the deposits and to elucidate the deposition mechanism.
