Abstract
Isothermal data of superficial tension of solutions of surfactant mixture and low-temperature nitrogen sorption of multidimensional porous silica received by template synthesis prove complementarity of its properties and properties of SAA micelles. The measured isotherms of gas sorption belong to IV Type inherent in mesoporous adsorbents. The BET specific surface area is 600–800 m2/g, and the Gurvich pore volume is 0.7–1.0 cm3/g. With increase in mole fraction of nonionic component these values decrease, the ordered texture of SiO2, characteristic of MCM-48 mesoporous molecular sieve, collapses, d211-spacing becomes < 3.31 nm, and NLDFT distribution is transformed from monomodal to polymodal one.
