Abstract

In order to inhibit the photocatalytic degradation of organic material supports induced by small titania (TiO₂) nanoparticles, highly photocatalytically active, commercially available P25-TiO₂ nanoparticles were first modified with a thin layer of (3-aminopropyl)triethoxysilane (APTES), which were then deposited and fixed onto the surface of paper samples via a simple, dip-coating process in water at room temperature. The resultant APTES-modified P25 TiO₂ nanoparticle-coated paper samples exhibit much greater stability to UV-illumination than uncoated blank reference paper. Very little, or no, photo-degradation in terms of brightness and whiteness, respectively, of the P25-TiO₂-nanoparticle-treated paper is observed. There are many other potential applications for this Green Chemistry approach to protect cellulosic fibres from UV-bleaching in sunlight and to protect their whiteness and maintain their brightness.
