- Osaka Metropolitan University published a review in Chemical Reviews summarizing the biocatalysts used in semi-artificial photosynthesis, a hybrid field that combines natural photosynthesis with synthetic photosensitizers to produce fuels and value-added chemicals from sunlight.
- Professor Yutaka Amao of OMU's Research Center for Artificial Photosynthesis authored the review, which frames semi-artificial photosynthesis as a component of Carbon Dioxide Capture, Utilization, and Storage (CCUS) technology.
- Natural photosynthesis converts only about 1-2% of incoming light into sugar, a ceiling the review argues semi-artificial systems can surpass by absorbing a broader spectrum of sunlight through artificial pigments.
- Semi-artificial photosynthesis merges synthetic photosensitizers with biocatalysts into reaction systems that possess properties not achievable by either component on its own, per the review.
- Amao said the technology is "expected to increase in value as a CCUS technology" and could evolve into a method for long-term fixation of CO2 into organic molecules usable as valuable substances.
Why it matters: By consolidating the biocatalyst landscape into a single Chemical Reviews paper, OMU gives carbon-capture researchers a reference point for scaling photo/biohybrid systems—Amao positions the field as a future CCUS pathway capable of fixing CO2 into useful molecules, though the source offers no commercial timeline or efficiency benchmark for the technology.
