Realization of light energy conversion/storage type �artificial photosynthetic systems� that synthesize hydrocarbon fuels and oxygen from carbon dioxide and water or decompose water into hydrogen and oxygen using solar energy is an ultimate dream for humankind, and is expected to lead to a fundamental solution to the problems of energy shortage and global warming.This talk will introduce the latest research activities in our group1-13), focusing on our challenges on the scientific and technological possibilities of artificial photosynthetic system for solar fuel conversion offered by semiconductor photocatalytic materials. Efforts to explore suitable materials and to optimize their energy band configurations for specific applications, and the design and fabrication of advanced photocatalytic materials in the framework of nanotechnology will be introduced, taking examples of recent research progress on Ag3PO4 and other newly developed materials. Many of the most recent advances in photocatalysis have been realized by selective control of the morphology of nanomaterials or by utilizing the collective properties of nano-assembly systems. The current theoretical understanding of key aspects of photocatalytic materials, as well as the crucial issues that should be addressed in future research activities will also be introduced and discussed.
