METHOD FOR PRODUCING AN ELECTRODE WITH NANOMETRIC STRUCTURE AND ELECTRODE WITH NANOMETRIC STRUCTURE

摘要

A method for manufacturing a nano-structured electrode, comprising the steps of providing a nano-porous matrix (6) having at least one active surface (7) and a plurality of substantially cylindrical pores (8) with diameter of nanometric size, providing a first electrolytic cell (9) containing an electro-deposition bath comprising a first electrolytic solution containing metallic salts, coupling of a first substrate (5) in a first electrically conductive material to said active surface (7) of said matrix (6), immersing said active surface (7) coupled to said first substrate (5) into said first electrolytic cell (9), growing nanowires (3) in a metal alloy of said salts inside said cylindrical pores (8) by feeding with a potentiostatic or galvanostatic current to promote the growing of the nanowires directly on said first substrate (5) and define a nano-structured charge collector, a step of removing said nano-porous matrix (6) from said collector being also provided to realize the electrode.
