▎ 摘　　要

NOVELTY - The graphene composite metal oxide electrode comprises a titanium substrate and a composite coating on a surface of the titanium substrate. The composite coating is coated with a lower metal oxide layer from the bottom to the top. The graphene is filled with a porous metal oxide layer composed of graphene and metal oxides and an upper metal oxide layer. The upper and lower metal oxide layers contain one or more of ruthenium, iridium, tin and titanium oxide. The titanium substrate is a plate or a mesh of titanium or a titanium alloy. USE - Graphene composite metal oxide electrode for use in chlor-alkali production (claimed). Can also be used in electro-winning metallurgy, electroplating, alkali preparation, waste water degradation, and organic synthesis fields. ADVANTAGE - The surface of the electrode is loose and porous, and the bonding force between the coatings is improved after adding graphene. The electrode preparation method is simple and easy to operate. The electrocatalytic activity is improved, the chlorine potential is lowered and the oxygen evolution potential is improved. The graphene composite metal oxide electrode utilizes the synergistic effect between titanium, graphene and the metal oxide layers to provide high performance to the titanium, graphene and metal oxide layers. The graphene composite metal oxide electrode can be featured with electrocatalytic activity, corrosion resistance excellent impact resistance, improved current efficiency and long service life. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a preparation method of graphene composite metal oxide electrode. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the graphene composite metal oxide electrode. (Drawing includes non-English language text)
