Investigation on Synthesis , Characterization and Photo catalytic properties of nano Composite Perovskites SrTiO3 /Zn2TiO4 for degradation of Congo Red

The perovskite phase formation of nanoparticle powder of strontium titanate / Zinc Titanium Oxide was investigated. Nanopowder of SrTiO3 /Zn2TiO4 was synthesized by hydrothermal method using the NaOH mineralizer [1]. The structure, phase formation and morphology of nanocomposite powder characterized using the X-ray diffraction technique (XRD), Fourier transformation infrared (FT-IR) spectroscopy, Energy-dispersive X-ray spectroscopy (EDX), Scanning Electron Microscope (SEM). Our results indicated that, the phase structure of the SrTiO3 /Zn2TiO4 nanoparticles is in cubic perovskite phase. The photocatalytic activity of SrTiO3 /Zn2TiO4 was evaluated by performing photodegradation of congo Red dye under sunlight irradiation. This study indicates the potential use of high aspect ratio (96%) SrTiO3 /Zn2TiO4 nanoparticle for removal of congo Red pollutions[2].
