Photocatalytic activity of TiO2 immobilized on glass beads

This paper reports the study of the photocatalytic activity of immobilized pure and boron-modified TiO2 on glass beads. In situ formation and a dip-coating technique fixing catalyst onto the support surface was used. The photoreactor consists of a cylindrical quartz tube (i.d. 40 mm, length 100 mm) and was packed with the immobilized catalyst. The photocatalytic activity was determined by the degradation of phenol in water (0.21 mmol/dm3). The pure TiO2 catalyst could be reused for at least 3 cycles.
