Micro- and nano-porous metallic structures.

摘要

Micro- and nano-porous metallic structures are produced by contacting an alloy of at least two metals having different electrochemical activity in predetermined proportions with an electrolyte and applying an electrochemical potential to said electrolyte wherein said alloy acts as the anode until all or a portion of the more electrochemically active metal is dissolved from the alloy leaving porous metal. The resultant structure has substantially uniform and interconnected porosity in pore sizes ranging from 3 nanometers to 10 micrometers.
