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. Meanwh...
