The stabilization of ruthenium nanoparticles is achieved by using for the first time multiple donor coordination site-type ligands, the N-phosphanylamidines Image ID:c1nj20465c-t2. gif. These ligands, in which the donor sites are directly connected to one another, lead to the formation of small ruthenium nanoparticles in the size range 1. [...]

The size of ruthenium nanoparticles is governed by the degree of self-organization of the imidazolium based ionic liquid in which they are generated from (η4-1,5-cyclooctadiene)(η6-1,3,5-cyclooctatriene)ruthenium: the more structured the ionic liquid, the smaller the size.

Multielectron reductions such as the hydrogen evolution reaction (HER) play an important role in the development of nowadays energy economy. Herein, the application of the organometallic approach as synthetic method allows obtaining very small, ligand-capped but also highly active ruthenium nanoparticles (RuNPs) for the HER in both acidic and basic media.

Four different cathodes for the hydrogen evolution reaction (HER) have been developed by the decoration of commercial carbon microfibers with Ru nanoparticles (Ru NPs). Two types of carbon fibers have been used: pristine, as-received, carbon fibers (pCF) and carbon fibers modified by an oxidative treatment that led to the functionalization of their surface with carboxylic groups (fCF).

The performance of OER anodes based on supported nanocatalysts is highly dependent on the interactions taking place at the interface between the nanocatalyst and the employed conductive support. Herein, the versatility offered by the organometallic approach for the synthesis of metal-based nanostructures allowed preparing electrodes of tailored nanocatalyst-support interactions. [...]
