In this work we presents a gold complex self-assembled to a mesh of nanowires which function as a porous electrode. We show that a simple chemical process results in a highly conductive mesoporous structure. Using cyclic voltammetry, the specific surface area of the assembly was significant, measured to be around 4 m²/g. The surface area only depended upon the amount of gold complex used, and gold deposition could be done on any substance and surface geometries. This work present a new method for the fabrication of high surface area gold electrode which is robust, cheap and show high performance in terms of active surface area.
