ABSTRACT:
A process for the production of a zero valent metal from an aqueous solution of a salt of the metal comprises contacting the solution with polyacetylene for a period of time sufficient to reduce at least a portion of the metal salt to a zero valent metal while leaving the polyacetylene in a substantially non-doped state. The metal salt has a reduction potential of about +0.5V or greater.
