“…In comparison, Pt/TiO 2 catalytic activity decreases by about 40% already in the second cycle, but Pt/RGO retains good catalytic activity after three cycles of use in hydrogenation. A study of the catalytic properties of Pt/NB and Pd/ND (ND-nanodiamonds) in the hydrogenation of NB showed that the catalysts have high activity and stability, as well as selectivity: aniline is the only reaction product (no by-products formed, which was confirmed analysis of reaction mixtures by gas chromatography) [16][17][18][19] (fig. 1).…”

“…Hydrogenation reactions have been mostly catalyzed by supported Pd NPs and to a lesser extent using Ni NPs. In one of these studies, Pd NPs supported on D NPs exhibited excellent catalytic activity for the hydrogenation of CC and CC bonds ,, or nitrobenzene, as well as the hydrogenating amination of propanal with 4-aminobenzoic acid. , In a related work, Pd NPs (10–20 nm) supported on commercial D NPs (300 m 2 g –1 ) previously oxidized at 300 °C under air atmosphere have been reported to be highly stable as a hydrogenation catalyst at 600 °C without observing sintering . Later, Su and co-workers reported the higher activity of Pd NPs (∼4 nm) supported on commercial D NPs (BET 309 m 2 /g) with respect to an analogous catalyst based on AC to promote the hydrogenating denitrogenation of benzonitrile (Figure ).…”

Diamond Nanoparticles in Heterogeneous Catalysis

et al. 2020

The use of diamond nanoparticles in catalysis has attracted considerable interest during the last three decades since these materials have been made commercially available. Diamond nanoparticles have been employed as supports of a small metal or metal oxide nanoparticles, as scaffolds for covalent grafting of organic molecules or metal complexes, and as carbocatalysts by generating a few layers of sp 2 carbons or other heteroatoms on the external surface. This review describes the main structural and chemical properties of diamond nanoparticles that have led to the development of catalysts with superior activity with respect to the use of analogous catalysts based on other carbon allotropes, carbon materials or even some benchmark metal oxides. These diamond-based materials have found superior applications as catalysts, photocatalysts, and more recently as carbocatalysts.

“…Palladium NPs supported on nanodiamonds exhibit enhanced activity towards the hydrogenation of the C=C and C≡C bonds. They were also used in the hydrogenation of cyclohexene, allyl alcohol, nitrobenzene, azomethines, allyl alcohol, and simultaneously for the reductive amination of propanal with 4‐aminobenzoic acid. Careful study of these literature reports indicate that NDs are a good support for transition metals such as Pd.…”

Palladium Supported on Nanodiamonds as an Efficient Catalyst for the Hydrogenating Deamination of Benzonitrile and Related Compounds

et al. 2016

View full text Add to dashboard Cite

Palladium nanoparticles were successfully prepared on a nanodiamond (ND) support and used for the hydrogenating deamination of benzonitrile, aromatic imines, and amines for the first time. The developed methodology was further used for the in situ conversion of aldehydes into hydrocarbons, including a biomass‐derived model compound. The activity of the catalyst was compared with palladium supported on activated carbon (AC) under identical conditions and the performance of Pd/ND was found to be superior to Pd/AC. The origin of the difference in the catalytic performance was considered. Finally, an attempt has been made to understand the mechanism through the identification of the side products by GCMS analysis.
