Metal Foam Electrode as a Cathode for Copper

In this work, we have investigated the dependence of the electrochemical deposition of copper coatings on the geometry of the copper substrate (flat plates or 3D foams). Chronoamperometric measurements show that copper deposition occurs 3 times faster on copper foams than on a flat electrode with the same geometric area in the same potential range, making metal foams great electrodes for electrowinning.

Copper electrowinning: theoretical and practical design

2009-10-15  For the winning of copper by the addition of electrons [1] Cations go towards the cathode, and anions go to the anode. The working electrode is where reduction takes place and the counter electrode is where oxidation occurs. The working electrode is the cathode and the counter electrode the anode. For the general oxidation/reduction reaction: [2] Faraday’s Law gives the total amount of
