Small-angle X-ray scattering studies of morphology controlled nano ceria

Abstract

In this study, we investigated the structural characteristics of CeO2-xNaOH powders, via hydrothermal method, using Small-Angle X-ray Scattering (SAXS) to analyze the scattering behavior and gain insight into the ceria morphology. The results from both models revealed the presence of a twophase porous structure with a fractal interface in all CeO2-xNaOH samples. As the NaOH concentration increased, variations in the radius of gyration, fractal dimension, and other structural parameters were observed. These findings provide a deeper understanding of the structural properties of CeO2-xNaOH powders and the impact of NaOH content on their morphology, which could be relevant for potential applications in catalysis, sensing, and other fields.
