We report the significance of hydrothermal temperature of TiO2 nanoparticles on the crystallinity, band gap and the photocatalytic degradation of congo red dye. These nanoparticles are synthesized by hydrothermal method at 120 ˚C, 140 ˚C and 160 ˚C. The anatase phases of the samples are confirmed from the X-ray diffraction pattern and the surface morphology […]
