Mesoporous solids include metal oxides, silica, phosphates and other materials. They may contain various acidic and basic sites which are, in combination with metal nanoparticles, metal atoms, functional groups, etc., could be efficient multifunctional catalysts for cascade reactions. In this shot review, the most important aspects of such catalysts that furnish their catalytic activity and selectivity for cascade reactions in biomass processing discussed. A combination of one metal with another or with metal oxid...

JOINT IMMOBILIZATION OF TWO OR MORE ENZYMES ON DIFFERENT CARRIERS

(STEF92 Technology, 2025-08-15, Ольга Валентиновна Гребенникова, Александрина Михайловна Сульман, Valentina G. Matveeva, Vladimir Molchanov)

Multi-enzymatic cascade reactions, that is, the integration of several biocatalytic transformations occurring simultaneously, offer a wide range of possibilities and new ways to synthesize products with high added value. Such systems improve biocatalytic processes by saving time and reducing waste, while being self-sufficient in terms of requirements for related factors. As a more environmentally friendly and sustainable alternative method for the production of chemicals and biological products increases in import...

SYNTHESIS OF MANNITOL FROM INULIN USING A MAGNETIC CATALYST

(STEF92 Technology, 2025-08-15, Oleg V. Manaenkov, Olga Kislitsa, Аntonina А. Stepacheva, Valentina G. Matveeva, Mikhail G. Sulman, Mikhail Sulman)

Mannitol is an important raw material in the production of resins, lubricants, coatings, surfactants, explosives, cosmetics and drugs. One of the promising ways to obtain it is the catalytic conversion of inulin, a natural polyfructosan found in large quantities in some agricultural crops. In this study a Ru-containing magnetic catalyst was proposed for the process of hydrolytic hydrogenation of inulin to mannitol. Under optimal reaction conditions a high mannitol selectivity of 44.3 % was obtained 100 % conversio...
