Synthesis and Characterization of Fe-Doped CaTiO3 Polyhedra Prepared by Molten NaCl Salt

CaTiO3 as one of the perovskite-based photocatalysts has a band gap energy 3.5 eV (~354 nm), thus will work at ultraviolet light region. One strategies to decrease is doping metal. In this research, was doped by Fe element purposes decreasing its energy. compounds were synthesized using molten NaCl salt method. The diffractogram samples showed that Fe-doped crystal successfully prepared. Meanwhile, SEM images particle shape regular polyhedral morphology, and Fe3+ caused size agglomerated. UV-Vis DRS spectra Fe-dopant revealed absorption visible range wavelength.
