Abstract

The molten salt synthesis has been known as an eco-friendly synthesis method because it does not produce hazardous waste and also, there is no requirement for a high calcination temperature. In this research, we synthesized SrBi4Ti3.95Fe0.05O15 photocatalytic material via the molten salt method using NaCl, KCl, and NaCl/KCl salt. The diffractogram sample showed that SrBi4Ti3.95Fe0.05O15 product obtained using KCl salt had successfully obtained with no impurities, but the SrBi4Ti3.95Fe0.05O15 product synthesized using NaCl salt has found an impurities phase of Bi4Ti3O12 and TiO2 (brookite). SrCO3 impurities was also found on SrBi4Ti3.95Fe0.05O15 product that was synthesized using NaCl/KCl salt. The micrographs showed that the sample's morphology is plate-like and still found agglomeration. The results of the Kubelka-Munk calculation showed that the SrBi4Ti3.95Fe0.05O15 has a band gap energy of about 2.32–2.55 eV.
