Cyclic Electrodeposition of PtCu Alloy: Facile Fabrication of Highly Porous Platinum Electrodes

Abstract
Cyclic electrodeposition of platinum and copper enables the fabrication of high surface area electrodes (roughness factors of >3000) by multiple alternation of alloy co‐deposition and dealloying of copper from the just‐fabricated alloy layers. The underlying processes, resulting electrode structures, and their applicability to potentially implantable glucose fuel cells are discussed.
