Structural, Optical and Photocatalytic Properties of SrTiO3 Perovskite obtained by Solvothermal Method

Abstract

The Solvothermal method was employed to produce bare TiO₂ nanoparticles and 5wt% SrTiO₃. The resultant samples were investigated using various instruments including X-ray diffraction (XRD), UV- Visible spectroscopy (UV), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX), and high-resolution transmission electron microscopy (HRTEM). The growth and crystallization of SrTiO₃ were analyzed using XRD. The SEM investigation revealed the spherical shape and aggregation of the nanoparticles, and the sample optical bandgap energy was found to be 3.2 eV. The maximal photodegradation efficiency of Congo red dye was achieved by the action of the valence band holes.
