Morphology of aluminium electrodeposited on aluminium from AlCl3+urea solvate ionic liquid

Abstract

The ionic liquid, made of urea and AlCl3, known as deep eutectic solvent (DESs) has already shown to be low‐cost electrolyte suitable for aluminum electrodeposition. By applying appropriate potentiostatic or galvanostatic electrolysis regime, aluminium is successfully electrodeposited from the deep eutectic solvent onto aluminium substrate at nearly room temperatures. Morphologies of the produced deposits were characterized by scanning electron microscopy (SEM) and chemical composition by energy-dispersive X-ray (EDX) analysis. The electrodeposited aluminium displayed different morphology depending on the deposition conditions applied.
