Dry methane reforming in conventional and micro-channel reactor systems

Syngas is a platform mixture of hydrogen (H2) and carbon monoxide (CO). By producing an appropriate ratio of H2/CO, syngas can be directly utilized in the fine chemical industry. With a promising recycle of carbon as well as mitigation of greenhouse gases, further limitation of global warming can be efficiently achieved by implementing three important strategies: (i) effective carbon capture and storage (CCS), (ii) development of efficient renewable energy, and (iii) enhanced end-use energy products. CO2 conversion represents an advanced step towards the production of high value-added products.

The combined effort of researchers from the Department of Inorganic Chemistry and Technology (D09) and Faculty of Chemistry and Chemical Technology, University of Ljubljana, was performed regarding the development of a micro-channel reactor system to study low-temperature dry reforming of methane.

Shape-selective activation of C-H bonds in synthesis of biaryls

Andraž in Gregor of the Department of Inorganic Chemistry and Technology (D-09) participated in an interesting study of the shape-selective activation of inert C-H bonds to oxidatively couple two toluene molecules.

Oxidative coupling of simple aromatics allows for a cost-effective synthesis of biaryls. However, utilization of this technology is severely hampered by poor regioselectivity and by the limited stability of state-of-the-art homogeneous Pd catalysts. The authors showed that confinement of cationic Pd in the pores of a zeolite enables a selective activation of C-H bonds, where selectivity is determined by the shape of the zeolite pores. The concept was demonstrated with the synthesis of 4,4'-dimethylbiphenyl using the Pd-zeolite Beta as guest-host heterogeneous catalytic system. Out of six possible isomers, 4,4'-dimethylbiphenyl is produced with high selectivity (80%). Andraž and Gregor relied on NMR measurements to determine the proximities of neighbouring Pd(OAc) fragments and their bonding to the zeolite framework. The work was described in an article published in Nature Catalysis (IF=30,5).

Efficient removal of perfluorinated contaminants

Through solid-state NMR measurements, Andraž and Gregor elucidated the way in which the molecules of perfluorooctanioc acid were adsorbed into all-silica zeolite Beta. They showed that the hydrophobic chains of the molecules were positioned in the straight channels of the zeolite and the carboxylic heads, forming hydrogen bonded pairs, in the intersections. This resulted in a very favourable adsorption enthalpy. Additionally, the helical conformation of the chains made a very tight packing at maximal capacity sterically possible. This explained the exceptionally high affinity and selectivity of all‐silica zeolite Beta for perfluorinated compounds, because of which this unusual zeolite became the lead candidate for combating the pollution with perflourinated compounds.

Catalyst for air cleaning with synergistic effect

Researchers of the department D-09 Petar Djinović, Alenka Ristić, Tadej Žumbar, Nataša Zabukovec Logar and Nataša Novak Tušar with coauthors from the Department of Catalysis and Chemical Reaction Engineering (D13), Department of Materials Chemistry (D10) and Bulgaria published on the results of this research in the journal Applied Catalysis B Environmental. Environment-friendly and stable bimetal catalyst on porous support for total oxidation of VOC in industrial waste air was synthesized and its structure-property-performance relationship was determined. The results are an importand contribution to the research area of bimetal catalysts on porous supports with synergistics effect. Such catalysts can be used also in total oxidation of organic pollutants in wastewater or in selective oxidation in catalytic biomass conversion to chemicals or fuels.

A metal-organic catalyst for C-H bond activation

Andraž and Gregor used solid-state nuclear magnetic resonance spectroscopy to thoroughly characterize the structure of a new efficient catalyst for the nondirected oxidative alkenylation of arenes. The catalyst is based on the porous metal-organic material MOF-808, functionalized by the tetrahydrothiophene-2,5-dicarboxylic acid ligands, which effectively entrap and stabilize Pd(II) centers.
