Chemoselective Liquid Phase Hydrogenation of 3-Nitrostyrene over Pt Nanoparticles: Synergy with ZnO Support

Lioubov Kiwi, Charline Berguerand, Fernando Cardenas Lizana, 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 ...

Pt-Zn nanoparticles supported on porous polymeric matrix for selective 3-nitrostyrene hydrogenation

Lioubov Kiwi, Charline Berguerand, Fernando Cardenas Lizana, 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 ...

Increasing Pt selectivity to vinylaniline by alloying with Zn via reactive metal-support interaction

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 ...

Structure sensitivity of selective acetylene hydrogenation over the catalysts with shape-controlled palladium nanoparticles

Lioubov Kiwi, Rocio Micaela Crespo Quesada, Artur Yarulin

The structure sensitivity of acetylene hydrogenation on catalysts with controlled shape of palladium nanoparticles was studied. Palladium particles of cubic (Pd-cub), cuboctahedral (Pd-co) and octahedral (Pd-oct) shapes were obtained by a colloidal method. ...
