  • ABSTRACT The photocatalytic degradation of methylene blue dye under visible light has been investigated using chromium modified titanium dioxide supported on zeolite (Cr- TiO:lzeolite). The photocatalyst was prepared by sol-gel method and characterized .by X-ray diffraction and SEM. The' rate of photodegradation of dye was monitored spectrophotometrical/y.The effect of pH, dye concentration,amount of photocatalyst and intensity of light on the rate of photocatalytic reaction was observed. The results showed that the use of Cr-doped Ti02 increased the rate of photocatalytic degradation of methylene blue as compared to untreated Ti02. The photocatalytic mechanism of Cr-Ti02 catalyst has been tentatively discussed. Keywords: Methylene ,blue, zeolite, chromium, photocatalytic degradation
