dc.description.abstractHexaaluminates are drawing attention due to their exceptional mechanical and thermal stability. They can be proposed for applications as catalysts or catalyst support materials in high-temperature reactions. In this study, various LaFexAl12-xO19 samples (x = 0.25, 0.5, 1, and 2) have been synthesized using the sol-gel method. Subsequently, these hexaaluminate samples were impregnated with cobalt oxide to form more active centers on the hexaaluminate support. The influence of the iron (Fe) content on the crystal structure, redox properties, and oxygen immobility has been investigated through X-ray diffraction, hydrogen temperature-programmed reduction, and oxygen temperature-programmed desorption techniques. Among the Co3O4@LaFexAl12-xO19 samples, those with x >= 1 exhibited a hexaaluminate crystalline structure, demonstrating a higher lattice oxygen mobility.
