Japan Technological Research Association of Artificial Photosynthetic Chemical Process
NEDO, in collaboration with the Japan Technological Research Association of Artificial Photosynthetic Chemical Process (ARPChem), the University of Tokyo, and TOTO Ltd., has developed particulate photocatalyst sheets that use solar energy to produce hydrogen from water (a form of artificial photosynthesis). The sheets are composed of two types of particulate photocatalysts and have a solar-to-hydrogen conversion efficiency of 1.1%.
The sheets are suitable for scaling-up and production cost reduction due to an extremely simple structure, providing the possibility of supplying low-cost hydrogen at a large scale.
The research results were published as an advance online publication in the U.K. scientific journal “Nature Materials”.
