Review summarizes photocatalyst and biocatalyst for artificial photosynthesis


A new review from Osaka Metropolitan University (OMU) summarizes the biocatalysts involved in semiartificial photosynthesis, an exciting research field that combines natural photosynthesis with artificial technology to efficiently generate fuels and useful substances from sunlight.

In nature, photosynthesis, the process by which plants convert solar energy into sugar, is not particularly efficient, with only about 1 to 2% of light being successfully converted. Semiartificial photosynthesis overcomes these limitations by combining synthetic photosensitizers and biocatalysts to construct reaction systems with unique properties.

A new review paper by Professor Yutaka Amao of the Research Center for Artificial Photosynthesis at OMU introduces the fundamentals of natural and artificial photosynthesis, using these as a basis for discussing semiartificial photosynthesis that utilizes biocatalysts and photocatalysts as part of Carbon Dioxide Capture, Utilization, and Storage (CCUS) technology.

“Semiartificial photosynthesis is expected to lead to technologies that achieve higher energy conversion efficiency than natural photosynthesis,” Professor Amao said. “This is accomplished through the absorption of a broad spectrum of sunlight using artificial pigments, combined with catalysts specialized for producing fuels and value-added substances.”

Furthermore, Professor Amao explains the current state of semiartificial photosynthesis, including research from his own group. “Semiartificial photosynthesis is expected to increase in value as a CCUS technology in the future,” he said. “It is expected that this technology will evolve into a method for long-term fixation of carbon dioxide into organic molecules, enabling its utilization as a valuable substance.”

The review was published in Chemical Reviews.

Testimonials

For well over a decade, in my capacity as a researcher, broadcaster, and producer, I have relied heavily on Alphagalileo.
All of my work trips have been planned around stories that I've found on this site.
The under embargo section allows us to plan ahead and the news releases enable us to find key experts.
Going through the tailored daily updates is the best way to start the day. It's such a critical service for me and many of my colleagues.
Koula Bouloukos, Senior manager, Editorial & Production Underknown
We have used AlphaGalileo since its foundation but frankly we need it more than ever now to ensure our research news is heard across Europe, Asia and North America. As one of the UK’s leading research universities we want to continue to work with other outstanding researchers in Europe. AlphaGalileo helps us to continue to bring our research story to them and the rest of the world.
Peter Dunn, Director of Press and Media Relations at the University of Warwick
AlphaGalileo has helped us more than double our reach at SciDev.Net. The service has enabled our journalists around the world to reach the mainstream media with articles about the impact of science on people in low- and middle-income countries, leading to big increases in the number of SciDev.Net articles that have been republished.
