| Abstract: | Titania-impregnated photocatalysts supported on glass fiber (GF) were prepared and employed in the photocatalytic oxidation of toluene. Amorphous titania sol (ATS) prepared from titanium isopropoxide was useful to impregnate titania on glass fiber in the shape of a thin film. TiO2/GF catalysts prepared by using the ATS showed better stability against water and vibration, but lower catalytic activity in the photo-oxidation of toluene compared to crystalline anatase powder (CAP) impregnated catalyst. Photocatalytic activity of the ATS catalyst was considerably enhanced by the addition of hydrogen peroxide, resulting in high activity comparable to that of the CAP catalyst. |
