Abstract :In this work, Ag doped nano TiO2 photocatalysts were synthesized in powder  form by hydrothermal method at 180 ºC in 120 min using different reduction agents. The  synthesized powders were characterized by powder X-ray diffraction insert ignore into journalissuearticles values(XRD);, Energydispersive  X-ray spectroscopy insert ignore into journalissuearticles values(EDS);, Surface area measurements insert ignore into journalissuearticles values(BET);, Transmission  electron microscopy insert ignore into journalissuearticles values(TEM); and scanning electron microscopy insert ignore into journalissuearticles values(SEM); analyses. The effect of  reduction agents on the morphological properties of Ag doped nano TiO2 has been studied.  We have been observed that the use of different reduction agents affects the particle size and  surface area. Ag doped nano TiO2 photocatalysts were coated to the ceramic pellets by dip  coating technique for photocatalytic study. Photocatalytic properties of the synthesized  powder were examined in a circulating aquarium filled with indigo blue insert ignore into journalissuearticles values(IB); solution under  UV irradiation. Periodical UV spectrophotometric analysis showed that indigo blue insert ignore into journalissuearticles values(IB); has  been degraded and its concentration has decreased under UV irradiation by time.
