Highly selective immobilized bimetallic Ni-Au nanoparticle catalyst for the partial hydrogenation of m-dinitrobenzene

Paul Joseph Dyson, Lioubov Kiwi, Oliver Anthony Beswick, Fernando Cardenas Lizana, Daniel André Samuel Lamey

Transition metal nanoparticles (NPs) are extensively used as catalysts for a wide and diverse range of organic transformations when immobilized on appropriate solid supports. We describe the development of a highly active and highly selective heterogeneous ...

Highly dispersed cobalt oxides nanoparticles on activated carbon fibres as efficient structured catalysts for the transfer hydrogenation of m-nitrostyrene

Paul Joseph Dyson, Lioubov Kiwi, Oliver Anthony Beswick, Alexander Parastaev

The facile preparation of structured catalysts featuring highly-dispersed non-precious metal (Fe, Ni, Co) oxide nanoparticles stabilized within a super-microporous network of activated carbon fibres (ACF) is described. The catalyst morphology was controlle ...

Structured Non-Noble Metal Catalysts for the Liquid-Phase Reduction of Nitroaromatics

Oliver Anthony Beswick

The industrial production of aromatic amines, essential intermediates for the synthesis of several drugs, dyes, pigments and agrochemicals, requires the use of heterogeneous catalysis. These molecules were formerly produced by the Béchamp reduction, a non- ...

Ni-based structured catalyst for selective 3-phase hydrogenation of nitroaromatics

Paul Joseph Dyson, Lioubov Kiwi, Thomas La Grange, Daniel André Samuel Lamey, Oliver Anthony Beswick, Félicien Muriset

We report herein on the development of Ni-based catalyst using activated carbon fibres (ACFs) as a structured support and its application for the three‐phase hydrogenation of nitroarenes (T = 353 K; P = 10 bar). It was shown that metallic Ni0 nanoparticles ...

Activated 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 ...

Iron oxide nanoparticles supported on activated carbon fibers catalyze chemoselective reduction of nitroarenes under mild conditions

Lioubov Kiwi, Oliver Anthony Beswick, Duncan Thomas Lindsay Alexander

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 ...
