Развитие Подходов К Формированию Платиновых Центров С Заданными Свойствами С Использованием Носителей Со Слоистой Структурой

Abstract

Specific properties of layered double hydroxides (LDH), directions of their use as supports and supports precursors for catalysts synthesis and the advantages of such catalysts in reactions of various types are considered. The ability to vary LDH the chemical composition (cationic layers, interlayer space) without destroying the structure of the material makes it possible to regulate its adsorption and acid-base properties, selectively realize various mechanisms for fixing the precursor of the active component to obtain highly disperse and stable supported catalysts. Approaches to the formation of particles of supported platinum with desired properties through changes in the anionic and cationic composition of LDH, using as an example the system Pt/MgAl(M)-LDH are proposed.
