The excellent hard radiation performance of the new GaliPIX³D detector enabled us to monitor the 24-hour synthesis process of nanoceria using the pair distribution function (PDF) method on an Empyrean diffractometer.
We performed an extensive in situ study of hydrothermal synthesis of nanoceria by a combination of X-ray diffraction and scattering techniques. The results of time-resolved small- and wide-angle X-ray scattering (SAXS WAXS) at variable temperatures suggest that at room temperature the active nucleation and growth of particles is occurring within the first 24 hours.
