Toward practical application of solar hydrogen
Our mission
We study particulate photocatalysts and reaction systems for sunlight-driven water splitting toward practical application of solar hydrogen. We have focused on oxynitride, nitride, and oxysulfide semiconductor material since the very beginning and have been developing them as photocatalysts for water splitting. Some of these materials absorb sunlight sufficiently and have band structures suitable for photocatalytic water splitting. We investigate the correlation among preparation methods, physical properties, and functionality of photocatalysts to improve their performance. We are also involved in the development of reaction systems suitable for large-scale application by taking advantage of the properties of particulate materials. Through these studies, we will contribute to solving energy and environmental problems.
