Abstract
The purpose of the present invention is to provide a formic acid production method and a formic acid production system with high production efficiency and in low cost. It is a formic acid production method comprising: preparing a mixed solution by mixing a solution containing an organic substance with a metal oxide powder having a photocatalyst function; and producing a formic acid by irradiating a light to the mixed solution. Also, it is a formic acid production system comprising: a raw material charging unit into which a solution containing an organic substance and a metal oxide powder having a photocatalyst function are charged; an artificial photosynthesis reaction unit for reacting a mixed solution of the organic substance and the metal oxide powder by irradiating a sunlight or a light to the mixed solution; and a formic acid recovery unit for recovering a formic acid from the mixed solution after an artificial photosynthesis reaction.
