Photocatalytic Materials Center
Aiming to produce efficient photocatalytic technology that can utilize visible light in order to ameliorate the global environment
Nowadays, environment pollution and energy crisis are worldwidely concerned. For a sustainable society, it is an urgent task to develop environment-benign purification technologies and manufacturing technologies of alternative clean energies. Photocatalysis is one of the most promising methods for both subjects. In this project, therefore, we focus on the fundamental research and development of new visible-light-responsive photocatalysts with high efficiency, aiming to make our contributions to a sustainable society.

“Photocatalysis” has potential to open one of the desirable technologies for further prosperity beyond the serious environmental pollution and next generation’s fuel resources of our planet. The photocatalysis is a nature phenomenon to promote chemical reactions on a surface of irradiated semiconductor. The essence of the photocatalysis is attributed to the property of photo-excited carriers (electrons and holes) with strong oxidization and reduction. That finally contributes to the decomposition, deodorization, and sterilization of the hazard organics, as well as decomposition of water to hydrogen and oxygen. We believe that novel photocatalytic materials which have further activities under visible light are going to contribute to the issues of the environment pollution and energy crisis. The Photocatalytic Materials Center which is composed of the following 3 groups has been founded at National Institute for Materials Science since April 2006. The focus is to develop highly efficient photocatalytic materials throughout our attempts from various aspects.

Groups
Advanced Materials Research Group
Photocatalysts having strong oxidation-reduction power are widely interested as environmental cleaning and energy conversion materials. The target of this Advanced Materials group is to develop new photocatalysts which can effectively utilize visible light included in not only solar light but indoor illumination.

Nano-structure Control Research Group
We seek to upgrade efficiency by controlling surface properties and structures (i.e., low-dimensional structures such as tunnels and layered crystals) at the nanometer level through application of fine-particle and surface science.
