Abstract
The possibility of the directed regulation of geometric parameters of the porous structure of mesoporous oxide inorganic materials based on the controlled variation of the pore diameter has been studied. The pore sizes have been varied on the basis of synthesizing aluminum-oxygen nanolayers of the given thickness on the surface of silica SBA-15 pores using the molecular layering method. This made it possible to increase the thickness of the wall separating them without changing the distance between the pore centers. A formula for determining the pore radius of the obtained material has been proposed on the basis of data on the interplanar spacing and pore radius of the initial silica and the specific porosity of the modified silica.
