Outline of Final Research Achievements

Two dimensional transition metal oxide sheets are expected to be utilized in various scientific fields because of their attractive features such as high surface areas and unique surface properties. However, improvements in the preparation method and application for the photocatalysts should be necessary. In this study, nanosheet composite photocatalysts are prepared toward the development of high functional photocatalysts.
Single molecular sheets of niobate are successfully prepared by a simple bottom-up approach and show superior photocatalytic activity for hydrogen evolution from water under UV light irradiation. Photocatalytic hydrogen evolution activity is much enhanced over composite of single niobate sheets with other materials such as graphene and MoS2 due to efficient electron transfer and charge separation.
