The Effect of Different Synthesis Procedures on the Texture Properties of MCM-41 Molecular Sieves Modified with Cesium

Nowak I., Michalska A., Ziołek M., Wieczorek W.

Polish Journal of Chemistry

2003

Vol. 77 / nr 5

591-600

The effect of MCM-41 modification by impregnation with cesium salt on the mesoporous structure has been studied by XRD, N2 adsorption/desorption, electron microscopy (TEM, SEM) and FT infrared spectroscopy in the skeletal region. The MCM-41 sample prepared at room temperature is more fragile to the modification and hydrothermal treatment than the siliceous material obtained by hydrothermal method.
