Porous metallic membrane

摘要

The present disclosure relates to a method of forming a metallic layer having pores extending therethrough, the method comprising the steps of: (a) contacting a cathode substrate with an electrolyte solution comprising at least one cation; reducing the cation to deposit the metallic layer on a surface of the cathode substrate; and (c) generating a plurality of non-conductive regions on the cathode substrate surface during reducing step (b); wherein the deposition of the metallic layer is substantially prevented on the non-conductive regions on the cathode substrate surface to thereby form pores extending through the deposited metallic layer. The present disclosure further provides a metallic porous membrane fabricated by the disclosed process.

1. A method of forming a metallic layer having pores extending therethrough, the method comprising the steps of:
(a) contacting a surface of a cathode substrate with an electrolyte solution comprising at least one cation; (b) reducing said cation to deposit the metallic layer on the surface of said cathode substrate; and (c) generating a plurality of non-conductive regions on the cathode substrate surface during reducing step (b); wherein: the deposition of the metallic layer is substantially prevented on said non-conductive regions on the cathode substrate surface to thereby form pores extending through the deposited metallic layer; and step (c) comprises a step of reducing an electron acceptor species contained within said electrolyte solution to dispose a non-conductive material on the cathode substrate surface to thereby generate said non-conductive regions.
