Abstract
The preparations of deodorizing fibers using TiO2 have been investigated. TiO2 is known to be an excellent photocatalyst for the degradation of organic and inorganic contaminants in water. TiO2 catalyst have been supported on the glass fiber by a dip-coating procedure. The resulting materials have been characterized by XRD and SEM. The immobilized catalysts were tested in the photocatalytic degradation of NH3, CH3SH and CH3CHO. The deodorant activity(D.A.) of these deodorizing fibers was measured by chromogenic gas detector tubes. The efficient deodorant activity results have been achieved through the increase of TiO2 sol concentration.
