Photodegradation of Reactive Golden Yellow R Dye Catalyzed by Effective Titania (TiO₂)

In the present research, Microwave Assisted Synthesis (MAS) method was applied to synthesize titania (TiO₂) at 150 degree Celsius in a range of 2-6 hours heating time. Each prepared TiO₂ were characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD) and nitrogen gas (N₂) sorption analysis (Brunaeur-Emmett-Teller (BET) and Barrett-Joyner-Halenda (BJH) calculation) techniques. The TiO₂ prepared by MAS 150 degree Celsius (4 hours) has emerged with the highest photo catalytic activity. Within 4 hours, the TiO₂ managed to catalyze the degradation of Reactive Golden Yellow R dye up to 98.51 %. This is because of the TiO₂ possessed high crystallinity of anatase phase, small crystallite size and high pore volume compared to other prepared TiO₂. (author)
