【 摘 要 】

Among photo-functionalized materials, photocatalysts in particular have beenresearched and developed by many researchers in various fields. After thediscovery of the Honda-Fujishima effect, their effectiveness became apparent,not only in water decomposition but also in sanitation and purification of theenvironment, for example, through antibacterial, self-cleaning, and deodorizingeffects as well as NOx removal. Recently, novel nano-size photocatalysts, withperformance superior to that of conventional types, have been developed, andexamples include nitrogen-doped photocatalysts responsive to visible light andbrookite-type photocatalysts with higher photocatalytic activity.Moreover, when applying a photocatalyst, it must be fixed to a substrate andblocking of the latter avoided. When photocatalysts with high photocatalyticperformance are fixed to plastics, papers and textiles, the substrate can bedecomposed and may be prone to peel off when exposed to irradiation with light,owing to the oxidation action of the photocatalysts. To prevent damage to thesubstrate resulting from photocatalytic oxidation, we have developed aphotocatalyst whose particles are coated with inorganic compounds that can beblended with organic substances.† This report was originally printed in J.
