Title: ELECTROCHEMICAL METHOD FOR THE PRODUCTION OF GRAPHENE COMPOSITES AND CELL FOR CONDUCTING THE SAME
Abstract:
A method of making an electrically conductive composite includes applying graphene oxide (27) to at least one non-conductive porous substrate (25) and then reducing the graphene oxide (27) to graphene via an electrochemical reaction. An electrochemical cell (10) for causing a reaction that produces an electrically conductive composite includes a first electrode (13), a second electrode (15), an ion conductive medium (17), electrical current in communication with the first electrode, and an optional third electrode having a known electrode potential. The first electrode (13) contains at least one layered electrocatalyst, which includes at least one non-conductive porous substrate (25) coated with graphene oxide (27) and at least a first and second active metal layer (29a, 29b) comprising a conductive metal in contact with the non-conductive porous substrate (25) coated with graphene oxide (27).
