β-Cyclodextrin-assisted preparation of hierarchical walnut-like CeOHCO3 and CeO2 mesocrystals

Hydrothermal synthesis of hexagonal CeO2 nanosheets and their room temperature ferromagnetism

“…The large number of defects result initial orthorhombic phase extremely unstable and dissolve easily and then recrystallize a higher quality crystal phase. We have succeed in converting that stable phase to unstable one and the same phenomenon also was detected by others [23]. The hexagonal phase is rather stable even prolonged the reaction time to a week.…”

A facile route for the fabrication of CeO2 nanosheets via controlling the morphology of CeOHCO3 precursors

“…The defects lead the phase easy to dissolve and then recrystallize a higher quality crystal phase. We succeed in converting the stable phase to unstable one and the same phenomenon was detected by others [22]. The hexagonal phase is rather stable even prolonged the reaction time to a week.…”

Radiation Chemistry Provides Nanoscopic Insights into the Role of Intermediate Phases in CeO2 Mesocrystal Formation

“…); (ii) precipitation of intermediates, such as Ce IV ‐hydroxide, and (iii) CeO 2 crystalline particle formation [8–12] . It has also been demonstrated that, depending on synthesis conditions, CeO 2 particles may form mesocrystals, highly‐ordered nanoparticle superstructures, which diffract as a single crystal [13–17] . In other words, mesocrystals constitute a special case of colloidal crystals, implying 3D translational order of various nanocrystals (primary particles) [18] .…”
