ABSTRACT

BaPbO₃ perovskite was prepared by the sol-gel method. The physical and chemical properties of catalyst were characterized by XRD, TEM, SEM, EDX and IR techniques. The photocatalytic activity of the sample was evaluated by photocatalytic decomposition of methylene blue (MB) dye under UV irradiation. The results of XRD indicate that the perovskite-type oxide (BaPbO₃) is crystal at 700 °C. The XRD, TEM and SEM revealed that BaPbO₃ particles are prepared in the nano-size regime. The results show that the degradation efficiency of methylene blue (MB) by BaPbO₃ is higher than rutile under similar conditions.

Keywords: Perovskite-type oxide, nanopowder, dye removal, methylene blue
