光触媒を用いる水からの水素生成の現状と展望

抄録

Prodiction of hydrogen from water by photocatalysis has been intensively studied in terms of photon energy utilization relating to the recent issue about alternating energy. The authors and other workers have found several active photocatalysis for overall water splitting being available under ultraviolet light irradiation. Some of such typical examples as well as the knowledge obtained from those studies were summarized. The presently demanded subject is to develop a photocatalyst which works under visible light irradiation. Recent develop concerning visible light responsive photopcatalysts was also presented.
