Electrochemical deposition of copper from copper nitrate aqueous electrolyte on graphite
substrate was investigated at current densities between 0.03 mA/cm2
- 1.36 mA/cm2 and
in the voltage range of 3 V to 15 V. The surface morphology and elemental composition of
the resultant deposit were characterized by electron microprobe analysis (EMPA). These
images illustrate the influence of current density on the shape of copper electrodeposited
on the electrode surface. Rods, polyhedral bodies, pentagonal pyramids, dendritics,
spiked spheres or cauliflower-like shapes are observed depending on the
electrodeposition conditions.
