- Achieved an astonishing 80% yield from acetone!
Summary
Professor Yutaka Amao (Research Center for Artificial Photosynthesis, Osaka Metropolitan University) and Graduate student Yu Kita (2nd year doctoral student at the Graduate School of Science, Osaka City University) have successfully synthesized 3-hydroxybutyric acid, a precursor for polyhydroxybutyrate (PHB), a water-insoluble, high-strength polyester used in packaging materials, with a remarkable 80% yield from acetone using a photocatalytic system and two enzymes, combining it with carbon dioxide. This research, which successfully synthesized a precursor for polyhydroxybutyrate (PHB), a biodegradable plastic, by artificially replicating the light and dark reactions of photosynthesis, utilizing sunlight to fix carbon dioxide, holds great promise for addressing both the plastic pollution and carbon dioxide reduction problems.
This research achievement was published online in "Chemical Communications" on September 7, 2022.
Financial Information
Part of this research was supported by the Academic Research Grant International Collaborative Research Acceleration Fund (International Collaborative Research Enhancement (B)) and the Basic Research (B) grant.
