doi:10.7517/j.issn.1674-0475.1999.01.25

Abstract

Abstract: The TiO₂/beads photocatalyst was prepared by the dip-coating technique using the hollow glass microbeads as a supporter and TiO₂/beads were characterized by XRD,SEM and TG-DTA. The effect of the different preparation conditions on the photocatalytic activity of TiO₂/beads was studied. The results showed that the photocatalytic activity of the TiO₂/beads was the highest when heat treatment at 600℃ for 5 h and the anatase phase and the rutile phase equal to 81to19.The transition temperature of samples from amorphous structure to the anatase phase was about 429℃. The photocatalytic activity of the TiO₂/beads was better when the anatase phase and the rutile phase coexist in a certain proportion.

Key words: titanium dioxide, hollow glass microbeads, photocatalytic activity
