▎ 摘　　要

NOVELTY - The electrode has an insulation substrate provided with an electric conduction layer and a selenium doped graphene. The electric conduction layer is formed by a physical deposition method on the insulation substrate. A main body is fixed to the electric conduction layer. An upper insulation substrate is made of glass. Thickness of the electric conduction layer is 18-22 mm. A tin dioxide is doped with fluorine and its thickness is 0.2-0.5 mm. USE - Selenium doped graphene electrode. ADVANTAGE - The electrode has simple structure, high cost and poor stability. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a selenium doped graphene electrode preparation method. DESCRIPTION OF DRAWING(S) - The drawing shows a top perspective view of a selenium doped graphene electrode.
