Effect of a template in the synthesis of multi-dimensional nanoporous aluminosilicate with the composition 25% Al2O3-75% SiO2

Samples of multi-dimensional nanoporous aluminosilicate with the composition (25% Al 2 O 3 –75% SiO 2 ) are synthesized using the template effect of supramolecular cetylpyridinium chloride. The samples are studied by means of low-temperature nitrogen static adsorption-desorption, X-ray diffraction, scanning electron microscopy, and FT-IR spectroscopy. Changes in the specific surface area, volume, and DFT distribution of mesopores are shown to depend on the template concentration, annealing temperature, and sample training temperature prior to analysis. When using 5.0% of the template, we observe the formation of an aluminosilicate mesophase with a three-dimensional MCM-48 cubic pore system, homogeneous mesoporosity, and the excellent textural characteristics typical of a well-organized cellular structure.
