Research Abstract

Nanosheet colloids of a photocatalytically active semiconducting oxide were prepared by exfoliation of layered niobate, and their photochemical functions were examined for three reactions related to photoenergy conversion : photoinduced charge separation between the nanosheet and an electron acceptor, photoinduced electron accumulation in the nanosheet, and photocatalytic hydrogen evolution from water. All of the reactions were largely affected by the addition of clay nanosheets. In particular, for the former reactions, yield and stability of the products greatly increased in the presence of an appropriate amount of clay. The results demonstrate that the nanosheet colloids can be applied to novel photoenergy conversion systems.
