Panasonic Photosynthesis System converts carbon dioxide …

Panasonic Corp said Monday it has developed an artificial photosynthesis system which converts carbon dioxide (CO2) to organic materials by illuminating with sunlight at a world’s top efficiency of 0.2%. The efficiency is on a comparable level with real plants used for biomass energy.

In the previous approaches so far, the systems have had complex structures such as organic complexes or plural photo-electrodes, which makes it difficult to improve their efficiency in response to the light. Panasonic’s artificial photosysnthesis system has a simple structure with highly efficient CO2 conversion, which can utilize direct sunlight or focused light.

molecular systems for artificial photosynthesis.

Panasonic is developing a form of artificial photosynthesis – the same system used by plants and other organisms to convert water and carbon dioxide into oxygen and carbohydrates, using sunlight. In the future, it is hoped this could be scaled up to industrial-sized facilities, absorbing CO2 from factories and other infrastructure.

Osaka-based Panasonic has come up with an artificial photosynthesis system that achieves an energy conversion efficiency of 0.3 percent.

Efficient harvesting of unlimited solar energy and its conversion into valuable chemicals is one of the ultimate goals of scientists. With the ever-increasing concerns about sustainable growth and environmental issues, numerous efforts have been made to develop artificial photosynthetic process for the production of fuels and fine chemicals mimicking natural photosynthesis. Despite the research progresses made over the decades, the technology is still in its infancy because of the difficulties in kinetic coupling of whole photocatalytic cycles. Here, we report a new type of artificial photosynthesis system that can avoid such problems by integrally coupling biocatalytic redox reactions with photocatalytic water-splitting. We found that photocatalytic water-splitting reaction can be efficiently coupled with biocatalytic redox reactions by using tetra-cobalt polyoxometalate and Rh-based organometallic compound as hole and electron scavengers, respectively, for photoexcited Ru(bpy)32+ dye. Based on these results, we could successfully photosynthesize a model chiral compound (L-glutamate) using a model redox enzyme (glutamate dehydrogenase) upon in-situ photo-regeneration of cofactors.
