Azo Dye Degradation Activity of Perovskite-Type Materials
In this work, we have prepared single-perovskite- type materials. This research deals with the photocatalytic degradation of synthetic organic dyes: Methylene blue (MB), Naphthol Green B (NG), and Rhodamine B (RDB). Materials used for these experiments are simple nanocrystalline oxide-based perovskites comprising transition metals and lanthanides which were synthesized via the modified citrate sol-gel method. Single perovskite CeNiO3 was used as a parent compound, and we further increased the configurational entropy by adding different lanthanide cations on Ce position and transition metal cations on Ni position. All the materials used for photocatalytic degradation were characterized by powder X-ray diffraction, thermogravimetric analysis, and Brunauer-Emmet- Teller surface area analysis. The photocatalytic activity was monitored during irradiation at the wavelength of maximum absorbance for each dye (663 nm for MB, 734 nm for NG, and 554 nm for RDB) using UV/Vis spectroscopy. The results indicate a reduction of maximum absorbance of tested dyes in the given time frame which confirms the efficiency of synthesized photocatalysts.
