Cationic and anionic microgels based on sulfonated polystyrene poly(ethylmethacryltetramethylammonium chloride) containing Pd Pt nanoparticles were used as templates along with polystyrene-block-poly(ethylene oxide) block copolymers for casting nanoporous alumina aluminosilica nanoparticles. The Pt-nanoparticle-containing consists of interpenetrating pores particles 7 nm in diameter (by X-ray diffraction) located the interpore channels. are smaller partially pore entrances...
Supercritical (SC) fluid technologies are well-established methods in modern green chemical synthesis. Using SC fluids as solvents instead of traditional liquids gives benefits higher diffusivity and lower viscosity, which allows mass transfer intensification and, thus, an increased production rate transformations. Therefore, a conjugation heterogeneous catalysis with media is large step toward chemistry. Tetralin (TL) important hydrogen donor solvent used for biomass liquefaction. In...
Here, the development of a new catalyst is reported for selective furfural (FF) hydrogenation to furfuryl alcohol (FA) based on about 7 nm sized Pd-Cu alloy nanoparticles (NPs) formed in inexpensive, commercially available micro/mesoporous hypercrosslinked polystyrene (HPS). A comparison catalytic properties as-synthesized and reduced (denoted "r") catalysts as well monometallic palladium NPs showed considerable enhancement performance Pd-Cu/HPS-r compared other studied, resulting 100 % FF...
This paper is devoted to the production of second generation biodiesel via catalytic hydrodeoxygenation fatty acids. Pd/C catalysts with different metal loading were used. The palladium characterized using low-temperature nitrogen physisorption and X-ray photoelectron spectroscopy. It was revealed that most active selective catalyst 1%-Pd/C which allowed reaching up 97.5% selectivity (regarding n-heptadecane) at 100% conversion substrate. Moreover, chosen more preferable according lower...
Abstract Crosslinked polymers are considered to be promising materials for supporting catalysts that effectively applied in different reactions. However, the application of polymer‐supported high‐temperature processes is limited by their temperature stability. Besides thermal degradation, changes can cause restructuring polymer network because valence angles and bond lengths. Thus, study influence on structure crosslinked styrene–divinylbenzene (StDVB) copolymers an important task. In this...

In this report, three technological modes for methanol-to-gasoline reaction in the presence of H-ZSM-5 catalyst are compared: (i) direct methanol transformation to hydrocarbons; (ii) two-step (methanol-dimethyl ether-hydrocarbons); and (iii) cascade pathway. Light hydrocarbon gases (methane, ethylene, propylene, isobutene) liquid aromatic hydrocarbons (benzene, toluene, xylene, cresol, durol, naphthalene, methylnaphthalene, ethyl isopropyl methyl etc.) were found be main products. The...
Abstract Hydrogenation of aromatic compounds is a widely used catalytic process in modern industry. Selective hydrogenation benzene (BZ)‐toluene (TL) mixtures an important industrial as it allows the purification BZ for further synthetic purposes. In this work, BZ‐TL mixture (at molar ratio close to 1) was studied varying reaction parameters (temperature range 100–180 °C and pressure 1–7 MPa) using Pt‐, Pd‐, Ru‐containing nanoparticles stabilized by amino‐functionalized hyper‐crosslinked...
This work is addressing the arenes’ hydrogenation—the processes of high importance for petrochemical, chemical and pharmaceutical industries. Noble metal (Pd, Pt, Ru) nanoparticles (NPs) stabilized in hyper-cross-linked polystyrene (HPS) were shown to be active selective catalysts hydrogenation a wide range arenes (monocyclic, condensed, substituted, etc.) batch mode. HPS effectively NPs during different medium (water, organic solvents) allowed multiple catalyst reuses.
Among different polymers nanostructured cross-linked aromatics have the greatest potential as catalytic supports due to their exceptional thermal and chemical stability preservation of active phase morphology. This work studies ability hyper-cross-linked polystyrene (HPS) stabilize small Pdn Ptn (n = 4 or 9) clusters. Unrestricted DFT calculations were carried out for benzene (BZ) adsorption at BP level theory using triple-zeta basis sets. The BZ rings (stepwise from one four) was found...
In recent decades, the interest of researchers has focused on development methods for obtaining alternative energy sources. Fischer-Tropsch synthesis is one a wide range hydrocarbons and their derivatives. Ru, Ni, Fe Co are widely used catalytically active metals in FTS. To increase activity catalyst, as well yield target products, promoters introduced into catalytic systems.
