Synthesis of Biomorphic Ceria Templated from Crucian Fish Scales
Biomophic ceria with nanocrystalline was successfully synthesized using crucian fish scales as template.Unique biomorphic microstructures were characterized by X-ray diffraction (XRD),field emission scanning electron microscope (FESEM),transmission electron microscopy (TEM) and nitrogen absorption-desorption technique.The obtained ceria material shows the repetitious biomimetic structure consisting of sheet with thickness of ca.80-100 nm and nanopores which had 2-10 nm apertures.The surface oxygen activity of fish scale-templated CeO2 was enhanced revealed by hydrogen temperature-programmed reduction (H2-TPR) mesurements,because of the higher surface area (113.5 m2/g) and smaller particle size (average of 8.2 nm).Those detailed investigation could infer that the biotemplate product exhibit better catalytic activity in CO oxidation reaction.
