Templated electrosynthesis is a simple and versatile method that has been widely used to form nanomaterials and porous structures in materials science. The technique permits dimension-controlled materials synthesis. A variety of templates have been employed to define the morphology of conductive materials in electrodeposition. The formation of those materials has triggered intensive study and development of various novel properties and potential applications. This review presents recent advances in templated electrosynthesis as a method to fabricate nanomaterials and porous structures.
