This photo was taken in the process of underpotential deposition of copper on gold surface. The anode is gold/silica, cathode is copper wire, and electrolyte is 0.5M CuSO4 solution. I have never expected this result. Ideally, the copper monolayer should be deposited on gold surface instead of grown copper branches with certain amount H2 gas evolving.
