摘要

The present invention relates to a novel visible light absorbing graphene-papyrinth photocatalyst, a method for regenerating an oxidoreductase cofactor using the same, and a method for producing methanol from carbon dioxide by an enzyme reaction using the same, -Teinpolinil photocatalyst; Oxidase type oxidoreductase cofactor; And redox mediators; A method for producing methanol from carbon dioxide by an enzyme reaction using a method of regenerating a coenzyme of an oxidoreductase comprising the step of adding a biocatalyst to a phosphate buffer solution and producing methanol by stirring under light irradiation in a carbon dioxide atmosphere will be. The lepin-isatinpyrin photocatalyst according to the present invention is capable of regenerating co-factors of redox enzymes with excellent conversion efficiency, enabling mass production and automation, and is economical and environmentally friendly since it does not incur additional energy costs by using solar energy . In addition, it can be usefully used to convert carbon dioxide, which is a warming gas, into methanol by an enzyme reaction using a co-factor regeneration method of the oxidoreductase.
