Facile synthesis of ordered CeO 2 nanorod assemblies: Morphology and reactivity

Steam Reforming of Methanol over Nanostructured Pt/TiO2 and Pt/CeO2 Catalysts for Fuel Cell Applications

“…Herein, since the aspect ratio of length to width is above 15, the primary exposed surface of ceria is along the length of the rods; hence rods expose their (111) planes, as it was observed in most of the obtained images. Facet (220) is observed in Figure 3b, indicating that the growth direction of the nanorods is the (110), in accordance with the literature [61,67,68]. Apart from the predominant (111) facet, (200) can be also distinguished in few cases, as also reported in the literature for hydrothermally synthesized CNRs [69,70].…”

Synthesis and characterization of nanoceria for electrochemical sensing applications

“…For instance, ceria nanorods were synthesized from cerium hexahydrate and urea with surfactant-free hydrothermal approach. 32 Single crystalline mesoporous cerium oxide nanospheres were produced with CeCO 3 OH by controlling the amount of urea as a structural directing agent. 33 Shape-specific nanoceria synthesized via hydrothermal method with cerium nitrate as precursors were precisely controlled by molarity of sodium hydroxide, reaction temperature, and pH.…”

Hierarchical, template-free self-assembly morphologies in CeO2 synthesized via urea-hydrothermal method

“…However, the elimination of Na + ions from the final solids is difficult and the presence of ions on the ceria surface negatively affects the reactivity of the material. In other studies, urea was used to obtain nanorods [12], acrylamide to get nano-cubes [13], templates as PVP (polyvinylpyrrolidone) to produce table-like nanostructures, triangular prism-like nanotubes [14], PVP K30 to obtain hierarchical microspheres [15], and PVA (polyvinyl alcohol) to obtain flower-like and pyramidal polycrystalline particles [16]. Hierarchical flowerlike microspheres of CeO 2 were obtained with N-containing organic compounds after calcination of CeOHCO 3 precursors [17].…”
