NEDO, the Japan Technological Research Association of Artificial Photosynthetic Chemical Process (ARPChem), the University of Tokyo, TOTO, Ltd., and Mitsubishi Chemical Corporation have successfully developed a photocatalytic panel reactor with a larger surface area at a lower cost, with an ultimate goal of implementing an artificial photosynthesis system for societal use.

The newly-developed reactor contains sheets fabricated by coating a particulate photocatalyst on substrate and splits water with a depth of only 1 mm. Compared with conventional reactors, it requires less water inside the reactor and can be produced with lighter and cheaper materials. Furthermore, NEDO and the other participants constructed a large prototype of a 1 m2 photocatalytic panel reactor and demonstrated that the reactor split water into hydrogen and oxygen under natural sunlight. This represents a major breakthrough providing a fundamental principle for system design and advances the concept of artificial photosynthesis toward practical implementation.

The results of this research were published on the website of the American science journal Joule on Wednesday, January 11 (EST).
