Outline of Final Research Achievements

In order to develop highly active photocatalysts for photocatalytic steam reforming of methane at low temperature, we examined to prepare some kinds of photocatalysts consisting of crystals such as titanates and tantalates. We employed a molten salt method, which is known as a good method to synthesize crystals, to prepare the photocatalysts with crystals and evaluate the photocatalytic activity and discuss the relationship between them. As a result, we successfully prepared photocatalysts having higher activity. In addition, we clarified a clear relationship between the crystallites size and the photocatalytic activity, which will widely contribute to the development of photocatalysis preparation in many reactions.
