中文摘要：
以鲫鱼鱼鳞为生物模板合成了仿生氧化铈；通过X射线衍射仪、场发射扫描电子显微镜、透射电子显微镜和N2吸附一脱附分析仪等对其结构与性能进行了表征。结果表明：所得氧化铈是由具有立方萤石结构的氧化铈组成，晶粒尺寸为5～7nm氧化铈中存在大量的微米及纳米孔，孔径集中分布于2～5nm；其在太阳光下表现出较强的光催化活性，150rain内其对酸性品红的降解率可达到909／5以上，远远高于市售氧化铈粉体的。
英文摘要：
The biomimetic CeOz was obtained by using fish scales as biotemplate, and its structure and properties were characterized by Xray diffraction, field emission scanning electron microscopy, transmission electron microscopy and nitrogen adsorption-desorption measuring. The results show that the CeOz was the cubic fluorite structure with grain sizes of 5--7 nm, and a lot of pores with 2--5 nm were found in it. The prepared CeO2 displayed the superior photocatalytic activity for the degradation of acid fuchsin under sunqight irradiation, with a degradation rate as high as 90o/oo within 150 rain.
