Electroless deposition
Usually an electrolytic cell (consisting of two electrodes, electrolyte, and external source of current) is used for electrodeposition. In contrast, electroless deposition uses only one electrode and no external source of electric current. However, the solution for electroless deposition needs to contain a reducing agent so that the electrode reaction has the form:
{\displaystyle {\ce {M^{\mathit {z}}+{}+Red_{solution}{\ce {catalytic~surface}}]M_{solid}{}+Oxy_{solution}}}} {\displaystyle {\ce {M^{\mathit {z}}+{}+Red_{solution}{\ce {catalytic~surface}}]M_{solid}{}+Oxy_{solution}}}}
