▎ 摘　　要

NOVELTY - Graphene-enhanced photocatalysis auxiliary electrolytic water hydrogen production anode comprises a base layer provided with periodic wedge-shaped grooves, a graphene layer placed on the base layer and a titanium dioxide layer placed on the graphene layer, where the material of the catalyst layer is metal oxide, metal nitride and metal sulfide, the precious metal is gold or silver and further comprises carbon nanotubes, which are placed on the surface of the titanium dioxide layer and in the grooves. USE - Used as graphene-enhanced photocatalysis auxiliary electrolytic water hydrogen production anode. ADVANTAGE - The anode: enhances the interaction between incident light and the titanium dioxide layer; enhances the life of photo-generated holes; improves the strong oxidation activity of the anode; enhances the oxygen evolution capability of the titanium dioxide layer; improves the hydrogen production efficiency of the device; and has simple preparation method and high hydrogen production efficiency. DESCRIPTION OF DRAWING(S) - The drawing shows a graphene-enhanced photocatalysis auxiliary electrolytic water hydrogen production anode.
