ABSTRACT
Electrodeposition (ED), or electrochemical deposition as the name suggests, is a chemical reduction process induced by electric current. In the ED method, a two-electrode or three-electrode setup is conventionally used. A rule that governs the amount of the substance deposited and gives a key idea on the electrodeposition process is Michael Faraday’s first and second laws of electrolysis. The electrode potential and standard electrode potential of the concerned metal(s) play a major role in the process of electrodeposition. The metal and the standard hydrogen electrode are immersed in the conducting electrolyte. The behavior of solvated ions in electrolyte changes especially when complexing agents are added and they transform the ions into complex ions. ED is a conventional and an effective route to synthesize materials with challenging and tunable physicochemical properties. It is clear that via the ED technique one can synthesize single-oriented films, bulk and nanocrystalline metals, alloys, semiconductors, and multilayers composites.
