Photochemical processes developed in composite based on highly separated metallic and semiconducting SWCNTs functionalized with polydiphenylamine

Arnaud Magrez

The electrochemical polymerization of diphenylamine (DPA) onto electrodes of Pt coated with highly separated metallic (98%) or semiconducting (99%) single-walled carbon nanotubes (SWCNTs) in the presence of H3PW12O40 was performed by cyclic voltammetry in ...

Pt-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 ...

A nanoporous molybdenum carbide nanowire as an electrocatalyst for hydrogen evolution reaction

Hubert Girault, Xile Hu, Micheal Diarmaid Scanlon

A highly active and stable electrochemical catalyst of nanoporous molybdenum carbide nanowires (np-Mo2C NWs) has been developed for hydrogen evolution reaction (HER). The np-Mo2C NWs were synthesized simply by pyrolysis of a MoOx,/amine hybrid precursor wi ...
