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.

One clean alternative to fossil fuels would be to split water using sunlight. However, to achieve this goal, researchers still need to fully understand and control several key chemical reactions. One of them is the catalytic oxidation of water to molecular oxygen, which also occurs at the oxygen evolving center of photosystem II in green plants and algae. [...]
