Abstract:
Due to the ability to control the structure and properties of nanocomposites, they are very promising for use as catalysts for petrochemical processes based on synthesis gas (mix of CO and H<sub>2</sub>), such as Fischer-Tropsch synthesis, methanol synthesis, dimethyl ether synthesis, etc. [1] The original approach to the synthesis of composite materials with high activity in reactions based on CO and H<sub>2</sub> was created in A.V. Topchiev Institute of Petrochemical Synthesis (Russia) [2,3]. Using active component metal-polymeric composite particles leads to formation of fundamentally new catalytic active particles with unique properties. The selectivity and activity of composites in reactions based on H<sub>2</sub> and CO can be controlled by the polymer nature, polymer concentration, and a method of introducing a polymer composition in the composite material. Synthesized composites were characterized by complex phys-chemical methods: magnetometry in situ, IR- spectroscopy, dynamic light scattering, and transmission electron microscopy. Nanoheterogeneous contacts distributed in solid organic matrix were synthesized by method of polymer-containing composite materials. Initial organic matrixes represent polyconjugated systems decomposing to carbon during formation of the catalyst. These particles of 10-20 nm in size formed metal from salts immobilized on polymers. The polymers' flexibility and its effect on coils formation was determined by molecular modeling method. [4] Analysis of the polymers folding into coils, and a comparative study of their geometry revealed significant differences of the final structure of the polymer molecules, forming a complex metal-containing particle - polymer structure.
