PHOTOCATALYST COMPOSITION, PHOTOCATALYTIC ACTIVITY IMPROVER AND PHOTOCATALYTIC ACTIVITY IMPROVING METHOD

摘要

PROBLEM TO BE SOLVED: To improve photocatalytic activity of TiOremarkably at minimum cost.SOLUTION: Photocatalytic activity of TiOcan be improved to the degree of three times by mixing micro-porous titanate nanofiber (MPTNF;H. Hattori, Y. Ide and T. Sano, J. Mater. Chem. A, 2014, 2, 16381) with TiOhaving photocatalytic activity such as P25. Even if another TiO-based material is mixed instead of MPTNF, such an activity improvement effect is not revealed.SELECTED DRAWING: Figure 2
