The development of new methods of microporous materials design is the result of
increasing interest to generation of effective techniques for separation and accumulation of
fine-molecule size gases. The intercalation of organic molecules in interlayer space of layered
10-14Å-wide aluminum silicate with the following carbonization of received organo-mineral
composite is one of the advanced directions of synthesis of the new materials with molecularsieving
properties.
The results of the texture analysis of carbon-mineral composites (CMC) and carbon
obtained from CMC after mineral matrix dissolving are presented in this report. The natural
aluminosilicate – montmorillonite (MMT) – has been used as mineral matrix. The monomers
(acrylamide and styrene) were intercalated in MMT interlayer space and their polymerization
was fulfilled at 80 o C during 17-24 hours. Modified MMT was purified from polymer formed
on the external surface of particles, dried in air at 100 o C (stage 1) and calcined in argon
atmosphere at 350-590 o C (stage 2).
Interlayer spacing d 001 determined by X-ray diffraction analysis method, specific surface
A BET and micropores specific surface (measured by CO 2 sorption at 273 K) of obtained CMC
are presented in the Table 1.
