PURPOSE: A novel graphene photocatalyst absorbing visible light, a regeneration method of oxidoreductase cofactor using the same, and a manufacturing method of formic acid from carbon dioxide with an enzyme reaction using the same are provided to be economic and environment-friendly, to enable the mass production and automation, and to be able to be usefully used in a novel manufacture industry in which artificial photosynthesis which selectively manufactures various compounds by fixing carbon dioxide which is global warming gas. CONSTITUTION: A novel graphene composite is represented by Chemical formula 1. The novel graphene composite is used as a photocatalyst absorbing visible light. A regeneration method of oxidoreductase cofactor comprises a step of inputting a phosphate buffer solution; oxidative oxidoreductase cofactor methyl viologen; at least one oxidation-reduction medium selected from the group consisting of a ruthenium (II) composite and a rhodium (III) composite; and the graphene photocatalyst absorbing visible light represented by Chemical formula 1 in a reactor, and stirring while applying light to produce a reductive oxidoreductase cofactor. |
