Abstract

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.

Key words: ordered mesoporous alumina, thermal stability, mesoporous structure

CLC Number:
