Fabrication of perovskite-type oxide La0.5Ca0.5CoO3-δ nanoparticles and its Dye removal performance

La0.5Ca0.5CoO3 perovskite-type oxide is prepared by sol-gel method. The physical and chemical properties of La0.5Ca0.5CoO3 were characterized by differential thermal analysis (DTA), X-ray diffraction (XRD), transmission electron microscopy (TEM), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX), Brunauer-Emmett-Teller (BET) method and IR techniques. The photocatalytic activity of the sample is evaluated by photocatalytic removal of Congo Red (CR) dye under UV light irradiation. The results of XRD and BET indicate that the perovskite-type oxide (LCCO) have a good crystal phase at 650 and 750 degrees C with large specific surface area. The DTA, XRD, TEM, SEM, and EDX data revealed that LCCO nanoparticles are prepared successfully via sol-gel modified pechini method. The result showed that the degradation efficiency of CR by LCCO is excellent under UV light irradiation under our experiment condition.
