Biotemplate Synthesis of Porous Ceria Fiber and Study on Its Catalytic Performance

摘要：

　　Hierarchical porous ceria with nanocrystalline was successfully synthesized using filter paper as biotemplate.Unique biomorphic microstructures were characterized by Field Emission Scanning Electron Microscope (FESEM),transmission electron microscopy (TEM) and nitrogen absorption-desorption technique.The obtained ceria material showed the repetitious biomimetic structure consisting of fibre with diameter of ca.1-3 μm and nanopores which had 2-4 nm apertures.The small crystallite diameter (6-8 nm) and the high specific surface area (71.3 m2·g-1) of porous CeO2 were measured by wide-angle X-ray Diffraction (XRD),high resolution TEM (HRTEM) and the BET method.While the concentration of acid fuchsine was 20 mg/L,the porous sample had a higher decoloring rate in a shorter time than others.The decoloring rate can reach 100% after 200 min.
