METHOD FOR GROWING METAL PARTICLES BY ELECTRODEPOSITION WITH IN SITU INHIBITION

摘要

The invention relates to a method for making an electronic and catalytic conductive electrode containing metal particles, including: a step of electrodepositing a metal salt for forming said metal particles at the surface of an electrode, characterized in that the step of electrodepositing the metal salt is carried out in the presence of a blocking chemical species having a high absorptive capacity at the surface of said metal particles and having an oxidation potential higher than the reduction potential of said metal salt, such that the blocking chemical species maintains the blocking capacity thereof during the reduction reaction of said metal salt, and such that the size of the formed metal particles constituting said electronic and catalytic conductive electrode is reduced; and a step of desorbing the blocking chemical species.
