Abstract
Abstract A process for depositing metal in the form of an interlayer within a solid matrix. The process is characterized in the use of electroactive transfer agents to carry electrons from the cathode to the desired locus within the matrix where the metal cation (M n+ ) is reduced to its zero-valent state. Also disclosed are composites of metallic-interlayer-containing matrices.
