Pd-Nanoparticles Confined Within Hollow Polymeric Framework as Effective Catalysts for the Synthesis of Fine Chemicals
Encapsulation of metal nanoclusters in porous solid polymer materials is a promising approach to combine the outstanding properties of both, heterogeneous and homogeneous catalysts. We report heterogeneous nano-engineered catalysts containing Pd-nanopartic ...
Springer/Plenum Publishers2016Pt-Zn nanoparticles supported on porous polymeric matrix for selective 3-nitrostyrene hydrogenation
Lioubov Kiwi, Fernando Cardenas Lizana, Charline Berguerand, Artur Yarulin, Irina Prokopyeva
We report the promoting effect of Zn on performance of Pt-based catalyst in liquid-phase hydrogenation of 3-nitrostyrene (3-NS) to 3-vinylaniline (3-VA). Bimetallic Pt-Zn nanoparticles (NPs) were prepared within the hypercross-linked polystyrene (HPS) supp ...
Elsevier2015Activated carbon fibers for efficient VOC removal from diluted streams: the role of surface functionalities
Lioubov Kiwi, Guillaume Bastien Baur, Oliver Anthony Beswick, Jonathan Spring
The effect of surface functionalities, specific surface area and pore size of activated carbon fibers (ACFs) on the adsorption of toluene and acetaldehyde, two volatile organic compounds (VOC), at low concentrations (similar to 80 ppmv) and short contact t ...
Springer2015Activated carbon fibers modified by metal oxide as effective structured adsorbents for acetaldehyde
Lioubov Kiwi, Guillaume Bastien Baur
Novel efficient adsorbents for acetaldehyde removal from diluted gas streams (similar to 1300 ppmv) have been developed. The adsorbents combine the properties of activated carbon fibers (ACF) and nanoparticles (NPs) of basic metal oxides (La2O3, CaO, MgO, ...
Elsevier Science Bv2015Activated carbon fibers for efficient VOC removal from diluted streams: the role of surface morphology
Albert Renken, Lioubov Kiwi, Guillaume Bastien Baur
The effect of the micropore structure of activated carbon fibers (ACFs) on the adsorption of toluene at low concentration (10-80 ppmv) was studied over two types of ACFs. Both adsorbents presented similar surface chemistry but different porous structure: o ...
Springer Verlag2015Chemoselective Liquid Phase Hydrogenation of 3-Nitrostyrene over Pt Nanoparticles: Synergy with ZnO Support
Lioubov Kiwi, Fernando Cardenas Lizana, Charline Berguerand, Artur Yarulin
Hydrogenation of 3-nitrostyrene was performed at T = 348 K and 10 bar over platinum nanopartides supported on several metal oxides. Pt/Al2O3 and Pt/C catalysts exhibited high activity giving 3-ethylaniline as the only product, while Pt/ZnO displayed high s ...

Lioubov Kiwi, Charline Berguerand, Artur Yarulin
The promoting effect of Zn on Pt-based catalyst was studied for the liquid-phase hydrogenation of 3-nitrostyrene (3-NS). The monodispersed Pt nanoparticles (ca. 2.3 nm) supported on ZnO catalyzed the target 3-vinylaniline (3-VA) formation (S3-VA = 97% at X ...
Elsevier2015Fine structuration of low-temperature co-fired ceramic (LTCC) microreactors
Albert Renken, Paul Muralt, Lioubov Kiwi, Thomas Maeder, Bo Jiang, Julien Haber
The development of microreactors that operate under harsh conditions is always of great interest for many applications. Here we present a microfabrication process based on low-temperature co-fired ceramic (LTCC) technology for producing microreactors which ...

Lioubov Kiwi, Duncan Thomas Lindsay Alexander, Oliver Anthony Beswick
Highly dispersed iron oxide (Fe2O3) nanoparticles (NPs) have been immobilized on structured supports of activated carbon fibers (ACF). Systematic catalyst characterizations suggest that ACF-based catalysts remain ultra-microporous after Fe2O3 NPs (similar ...
Elsevier Science Bv2015Hydrothermally-treated Na-X as efficient adsorbents for butadiene removal
Lioubov Kiwi, Jeremy Luterbacher, Florent Emmanuel Héroguel, Guillaume Bastien Baur, Jonathan Spring
An efficient adsorbent for butadiene was synthesized via soft hydrothermal treatment (2 h in boiling water followed by 1 h calcination at 573 K) of industrial Na-X. The adsorption capacity of the zeolite was studied in the low concentration range (20–300 p ...
