Abstract
A method of making an electrically conductive composite includes applying graphene oxide to at least one non-conductive porous substrate and then reducing the graphene oxide to graphene via an electrochemical reaction. An electro-chemical cell for causing a reaction that produces an electrically conductive composite includes a first electrode, a second electrode, an ion conductive medium, electrical current in communication with the first electrode, and an optional third electrode having a known electrode potential. The first electrode contains at least one layered electrocatalyst, which includes at least one non-conductive porous substrate coated with graphene oxide and at least a first and second active metal layer comprising a conductive metal in contact with the non-conductive porous substrate coated with graphene oxide.
