摘要：

The pore structure of mesoporous membranes coated oil silicon wafer was characterized by the adsorption of krypton at 77 K ill this Study. To establish the capillary condensation and evaporation conditions for krypton at this temperature, the adsorption of both nitrogen and krypton were first measured oil a series of Siliceous MCM-41, MCM-48 and SBA-15 reference samples. The adsorption and desorption transition of krypton were then correlated with the pore size deduced from the nitrogen isotherm. Finally, the obtained correlation was applied to estimate the pore size distribution of niesoporous films.
