Проведен низкотемпературный синтез мезопористых силикатов, содержащих d-металлы. Измеренные изотермы низкотемпературной адсорбции–десорбции азота, полученные хромо-, ванадо- и цирконосиликатными адсорбентами, относятся к типу IV(b) изотерм сорбции по классификации IUPAC. Изотермические кривые такого рода присущи мезопористым системам с типом M41S упорядочения составляющих элементов. Увеличение рН осаждения и рост содержания металла приводят к аморфизации образцов и искажению надмолекулярной рещетки с единой регулярной геометрией и дальним порядком.

Low-temperature synthesis of the mesoporous silicates containing d-metals is carried out. The measured isotherms of low-temperature nitrogen adsorption-desorption by chrome, vanadium and zirconium silicate adsorbents belong to Type IV (b) of sorption isotherms on IUPAC classification. Such isothermal curves are inherent in mesoporous systems with the M41S type of ordering of the making elements. Increasing рН of sedimentation and metal content lead to amorphization of samples and distortion of a supramolecular lattice with uniform regular geometry and a long-range ordering.
