Photoinduced Transformation of Silicone-modified TiO2

Photoinduced Transformation of Silicone-modified TiO2

Silicone-modified titanium dioxide (TiO2) was prepared by solid–liquid reaction between TiO2 powder and H-siloxane. The surface energy of the synthesized powder was found to increase upon irradiation, an effect that was determined through electron spin resonance and 29Si nuclear magnetic resonance s...

Zusammenfassung:Silicone-modified titanium dioxide (TiO2) was prepared by solid–liquid reaction between TiO2 powder and H-siloxane. The surface energy of the synthesized powder was found to increase upon irradiation, an effect that was determined through electron spin resonance and 29Si nuclear magnetic resonance studies to be due to photocatalytic oxidation of the silicone present on the TiO2.
