Abstract
AbstractMagnesium titanate (MgTiO3) has been successfully synthesized via the sonochemical method by using TiO2 (P25) and Magnesium nitrate (MgNO3)2.6H2O as precursors without any additional phases such as MgTi2O5 and Mg2TiO4. The synthesized nanoparticles were well characterized by optical methods using UV‐Vis diffuse reflectance spectroscopy (DRS) and Photoluminescence spectroscopy (PL). The morphology of MgTiO3 nanoparticles is irregular in shape with serious agglomerations were confirmed through SEM analysis. XRD confirms crystal structure and phase purity of MgTiO3 nanoparticles calcined at 700 °C for 2 hours. The calculated band gap energy of MgTiO3 nanoparticles has been found to be 3.05 eV. Using the prepared MgTiO3 nanoparticles, the photocatalytic activities were evaluated by following the degradation of Congo red dye under visible light. Moreover, the influence of various scavengers on the photocatalytic reaction were studied.
