▎ 摘　　要

NOVELTY - A photo-induced oxidation-reduction reaction electrocatalytic electrode is electrode of silver-graphene-copper structure in which bottom layer is copper thin film, intermediate layer is two-dimensional graphene layer and upper layer containing silver nanoparticles, is deposited on the surface of graphene. The copper thin film is current collector layer of silver-graphene-copper electrode. Built-in electric field is present in the graphene intermediate layer due to the contact of silver and copper with graphene, respectively. USE - Photo-induced oxidation-reduction reaction electrocatalytic electrode (claimed). ADVANTAGE - The photo-induced oxidation-reduction reaction electrocatalytic electrode generates oxygen-reduction reaction catalytic activity under solar excitation. DETAILED DESCRIPTION - A photo-induced oxidation-reduction reaction electrocatalytic electrode is an electrode of silver-graphene-copper structure in which bottom layer is copper thin film, intermediate layer is two-dimensional graphene layer and upper layer containing silver nanoparticles, is deposited on the surface of graphene. The copper thin film is current collector layer of silver-graphene-copper electrode. Built-in electric field is present in the graphene intermediate layer due to the contact of silver and copper with graphene, respectively. Silver nanoparticles are in contact with surface of graphene layer. The metal surface plasmon active layer has function of oxygen reduction reaction activity layer. An INDEPENDENT CLAIM is included for preparation of photo-induced oxidation-reduction reaction catalytic electrode.
