H2-Assisted Synthesis of Nickel Phosphide Nanocatalysts for the Hydrogenation of Phenylacetylene at Low Temperature
|
Nickel phosphide nanoparticles are valuable catalysts for hydrogenation reactions but typically require high temperatures and oleylamine, which limits surface reactivity. This study presents a new H2-assisted synthesis method at 200 °C using tri-n-octylphosphine (TOP) to produce well-crystallized Ni12P5 and Ni2P nanoparticles (5.5 nm). Characterization confirmed phase control through temperature, reaction time, and TOP/Ni ratio. The nanoparticles catalyzed phenylacetylene hydrogenation, even at temperatures as low as 0 °C with tri-n-butylphosphine co-catalyst. |

Two-Step Reduction Pathway of Copper(II) by Oleylamine for the Nucleation of Cu(0) Nanoparticles: A Joint Modelling and Experimental Study
|
We combine computational evaluation of Cu(II) and Cu(I) reduction and X-ray absorption spectroscopy monitoring of the oxidation state of copper to show that formation of Cu(0) nanoparticles starting from copper(II) acetylacetonate in oleylamine goes through a two-steps process, with the intermediate formation of Cu(I) complexes. Influence of phosphine ligands is demonstrated and usage of alternative copper sources is discussed. |
