| 摘 要： | 以硝酸铝为原料,聚乙二醇1540为模板剂,碳酸铵为沉淀剂,合成了有序介孔氧化铝。通过BET法比表面积测定以及透射电镜（TEM）、X射线衍射（XRD）分析，对合成的有序介孔氧化铝的结构特征进行了表征。重点考察了合成的有序介孔氧化铝在高温条件下的热稳定性。结果表明，合成的有序介孔氧化铝在高温条件下保持了良好的介孔结构，但比表面积有所降低。

| Abstract: | Ordered mesoporous alumina was synthesized with aluminum nitrate as raw material,PEG1540 as template,and ammonium carbonate as precipitating agent,and the product structure was characterized by BET,TEM,and XRD.Thermal stability of the product under high temperature was emphatically investigated.Results showed that the synthesized ordered mesoporous alumina maintained good mesoporous structure under high temperature,but its surface area was reduced. |

| Keywords: | ordered mesoporous alumina thermal stability mesoporous structure |
