FORMIC ACID PRODUCTION METHOD AND FORMIC ACID PRODUCTION SYSTEM

WIPO Patent Application WO/2021/145267

A1

The purpose of the present invention is to provide a formic acid production method and a formic acid production system that have low cost and high production efficiency. A formic acid production method characterized in that a metal oxide powder having a photocatalyst function is mixed with an organic-substance-containing solution to obtain a mixed solution, and formic acid is provided by irradiating the mixed solution with light. A formic acid production system characterized by comprising a raw material charging part into which are charged a metal oxide powder having a photocatalyst function and an organic-substance-containing solution, an artificial photosynthesis reaction part for irradiating the mixed solution of the organic substance and the metal oxide powder with sunlight or light to prompt a reaction, and a formic acid recovery part for recovering formic acid from the mixed solution following the reaction.
