Shcherban N. Structure, adsorption and catalytic properties of mesoporous materials based on zeolites (β, ZSM-5) and carbon (C, C3N4, SiC)

Scientific approaches to the creation of new micro-mesoporous zeolite- and carbon-containing materials have been developed and the influence of the structure (phase composition, texture) and acid-base characteristics of the surface of such materials on their adsorption and catalytic properties has been determined. Using the developed template methods, micro-mesoporous zeolite-containing materials (based on zeolites β and ZSM-5), which are characterized by developed mesoporosity and the presence of strong acid sites on the mesopore surface, were obtained. The possibility of purposeful formation with the regulation of the parameters of porous structure of carbon-containing materials (C, C3N4, SiC) by the selection of precursors, hard templates, activating agents with the obtaining of carbon based materials with a wide range of structural parameters was shown, as well as the influence of phase composition, porosity, acid/base properties of such systems on their adsorption (towards hydrogen and carbon dioxide), photocatalytic (reduction of carbon dioxide) and catalytic properties (in particular, in epoxides isomerization, arabinogalactan hydrolysis and hydrolytic hydrogenation, Knoevenagel condensation, betulin and n-butane oxidation) was found out.
