In this research, TiO2 photocatalyst was immobilized on borosilicate glass powder. The immobilization was carried out by mixing the TiO2 and borosilicate powders and then calcined at 600 to 800 °C for 1 h. XRD and SEM analysis showed uniform coating of the TiO2 particles on glass powder surface. The TiO2-coated glass powder showed good photocatalytic activity for methylene blue decomposition. The coated glass powder calcined at 650 °C showed highest activity. The reaction rate constant of the prepared catalyst, TiO2 and TiO2-P25 powders were 0.0111, 0.0341 and 0.0539 min-1, respectively. Photocatalytic activity decreased when the catalysts were re-used as a result of TiO2 particle detachment from the glass powder surface.
