Abstract

Anatase TiO2particles were uniformly and dispersedly deposited on the surface of glass fibers by a liquid phase deposition (LPD) method from a TiF4aqueous solution upon addition of H3BO3at 60 °C and then calcined at 60, 300 and 500 °C. The photocatalytic activity of the samples was evaluated by the photocatalytic oxidation of nitrogen monoxide (NO) in the gaseous phase. It was found that calcination temperatures obviously influenced the surface morphology and photocatalytic activity of the TiO2particles deposited on the glass fibers. At 300 °C, the TiO2samples exhibited the highest photocatalytic activity for the photocatalytic oxidation of NO and for the further conversion of NO2(from NO2to HNO3) due to the enhancement of crystallization of anatase TiO2particles. At 500 °C, the photocatalytic activity of the sample decreased significantly due to the dropping of many TiO2particles from the glass fibers. Compared with the TiO2film photocatalyst, the TiO2particles deposited on the glass fibers exhibited a lower deactivation rate.
