Effects of Atmosphere on Thermal Stability of Al-MCM-41
Source abstract
Abstract
The effects of atmosphere (O2, N2 and NH3) on the thermal stability of Al-MCM-41 were investigated for the first time. The thermal stability, characterized by BET surface area, pore diameter distribution and XRD patterns, showed greatly difference in samples treated under different atmosphere conditions. The samples treated in NH3 or N2 remained typical mesoporous structure up to 1010℃, but the mesoporous structure in the samples treated in O2 collapsed at temperatures larger than 900℃.
