    • Abstract

       

      A simple red-ox titrimetry method has been developed for rapid evaluation of the photo catalytic activity of TiO2 based photo-catalysts. The analytical procedure employs monitoring the kinetics of a simple one electron transfer reduction reaction of conversion of Ce4+ to Ce3+ in dilute aqueous solution in presence of sunlight. The photo-catalytic activity of TiO2 synthesized by two different routes was evaluated by the above technique. The effect of surface area, crystallite size and polymorphic contents on the photo-catalytic activity of TiO2 was also studied employing this method.
