Cobalt‐doped hybrid materials consisting of metal oxides and carbon derived from chitin were prepared, characterized and tested for industrially relevant nitrile hydrogenations. The optimal catalyst supported onto MgO showed, after pyrolysis at 700 °C, magnesium oxide nanocubes decorated with carbon‐enveloped Co nanoparticles. This special structure allows for the selective hydrogenation of diverse and demanding nitriles to the corresponding primary amines under mild conditions (e.g. 70 °C, 20 bar H2). The advantage of this novel catalytic material is showcased for industrially important substrates, including adipodinitrile, picolinonitrile, and fatty acid nitriles. Notably, the developed system outperformed all other tested commercial catalysts, for example, Raney Nickel and even noble‐metal‐based systems in these transformations.

“…Those catalysts are easily prepared by pyrolysis of a carbon source, such as Vulcan XC 72R, impregnated with in situ ligated Co and Fe, respectively. Similar materials containing nanoparticles supported on inorganic carriers and biomass‐derived catalysts were also studied . Based on these works, here we described the synthesis of cobalt‐containing materials and studied their catalytic performance in hydroformylation reactions.…”

“…The biowaste-derived cobalt chitosan catalysts used for the hydrogenation of C=C in 4-fluorostyrene yielded 81% of 1-ethyl-4-fluorobenzene in water but required elevated temperature and high H 2 pressure. 42 Copper nanoparticles supported on diamond nanoparticle annealed with hydrogen (Cu/DH) were investigated for the hydrogenation of 4-methoxystyrene. 43 The catalyst selectively hydrogenated the alkene group, but the presence of a strong electron-donating substituent caused the reaction to require 30 h to reach 60% conversion.…”

Colloidal Palladium Nanoparticles for Selective Hydrogenation of Styrene Derivatives with Reactive Functional Groups

This article presents the catalysis investigation of octanethiolate-capped palladium nanoparticles (C8 PdNP) and phenylethanethiolate-capped palladium nanoparticles (PhC2 PdNP) for chemoselective catalytic hydrogenation reactions of styrene derivatives in the presence of other reducible functionalities. The results show that the C8 PdNP is highly active under mild reaction conditions (room temperature and atmospheric pressure) and selective for hydrogenating monosubstituted alkene groups without reducing other reactive functional groups such as nitro, halo, carbonyls, and so forth. In comparison, the noncovalent interactions between surface phenyl ligands and aromatic substrates are found to hinder the hydrogenation activity of PhC2 PdNP.
