Outline of Final Research Achievements

In this research project, we created a novel nanohybrid photocatalyst in which heterogeneous metal oxide layers are alternately stacked on a nanometer scale. Specifically, by applying a click chemistry technique to layered metal oxide, photoinduced charge separation was controlled by introducing interlayer distance and dye molecules between the layers.
For layered tantalate and layered niobate for the application to photocatalyst, we investigated. Because of the difference in the conduction band potential of these layered compounds, it was possible to control the electron transfer which does not depend only on the interlayer distance. UV light induced charge separation in the heterostructes was evaluated by quantifying the amount of electrons accumulated in the conduction band of tungstate by near infrared diffuse reflectance spectroscopy.
