Измерены изотермы низкотемпературной адсорбции–десорбции азота титаносиликатными адсорбентами, осажденными на супрамолекулярном темплате с использованием сульфата титанила и силикатов натрия с модулем 1 и 3. Полученные изотермы относятся к типу IV(а) и IV(b) изотерм сорбции, по классификации IUPAC. Изотермические кривые такого рода присущи мезопористым системам с типом МСМ-41 упорядочения составляющих элементов, что свойственно адсорбентам с гексагональной упаковкой однородных цилиндрических капилляров. Характеристика титаносиликатных образцов путем анализа капиллярно-конденсационных свойств позволяет идентифицировать в них вторичные и третичные мезопоры щелевидной формы. 

Low-temperature isotherms of nitrogen adsorption-desorption of titanosilicate adsorbents deposited on supramolecular template using titanium sulphate and sodium silicate with module equal to 1 or 3 were measured. The isotherms measured belong to Types IV (a) and IV (b) adsorption isotherms by IUPAC classification. Titanosilicate materials with isothermal curves of such type can be offered as homogeneous adsorbents with mesoporous MCM-41 type of constituent element ordering, which is characteristic of mesoporous adsorbents with hexagonal packing of homogeneous cylindrical capillary. The characterization of titanosilicate samples by the analysis of capillary and condensation properties allows us to identify secondary and tertiary slit mesopores in them.
