| 摘 要： | 以硝酸铈为前驱物,以尿素为助剂,采用一种简单的模板法合成了介孔氮掺杂CeO2材料.利用X射线衍射仪(XRD)、吸附-脱附仪(BET)、透射电子显微镜(TEM)和傅里叶变换红外光谱(FT-IR)等设备对合成材料进行表征.多种测试结果证明:试验得到的纳米材料具有均一的介孔结构和较高的比表面积(124.8 m2·g-1)并掺杂了氮元素.同时,测定了介孔CeO2材料对于CO2的吸附性能,并研究了氮掺杂对CeO2材料的CO2吸附性能的影响.结果表明:相比未掺杂氮的介孔CeO2,氮掺杂的介孔CeO2具有更好的CO2吸附性能和循环吸附脱附性能.

| Abstract: | Novel mesoporous N-doped CeO2 has been prepared via a simple urea-assisted template method using cerium nitrate as precursor and urea as additives.X-ray diffraction,adsorption-desorption and FT-IR spectrum techniques are employed to characterize the samples.It is observed that the synthesized material has a uniform mesostructure with a high specific surface area(124.8 m2·g-1),and nitrogen element is introduced into it.The effects of mesoporous CeO2 without and with nitrogen element on the absoportion of CO2 are measured.The result shows that the synthesized mesoporous N-doped CeO2 applied as an adsorbent exhibits significant enhancement of CO2 adsorption performance compared with undoped mesoporous CeO2. |
