Abstract TiO 2 photocatalysts were prepared by hydrothermal method at temperatures of 110, 155, and 200°C for 24 hours, using KOH (5 mol/L):Na OH (5 mol/L) solution and anatase TiO 2 powder with an average particle size of 0.13 μm as precursor and by calcining at two different temperatures of 450 and 700°C. An overall photocatalytic removal efficiency of 93% was achieved for Rhodamine B dye under UV light irradiation by the photocatalyst obtained at synthesis and calcination temperatures of 155 and 700°C, respectively, which indicated a nanorod morphology with a mean diameter of about 34 nm.
