Ruthenium Nanoparticles

Ru nanoparticles belongs to the group of transition metals. It is considered a rare metal with limited availability. This may hamper broader commercial applications with ruthenium nanoparticles due to the high price (although it remains the cheapest noble metal) and high market volatility. Ruthenium nanoparticles is mainly used in technical devices and catalysts. Ruthenium is commonly added to alloys in small amounts due to its hardenability. This is the case for superalloys used for the production of turbine blades for jet engines. Strengthens rhodium, palladium, and platinum-based alloys used for permanent electrical contacts (modern spark plugs have electrodes coated with a Pt-Ru alloy; spring tips are made from ruthenium-containing alloys). Ruthenium nanoparticles is a polyvalent metal because it can readily adopt formal oxidation states over a wide range (II to VIII), resulting in a variety of complexes exhibiting interesting and often unique properties. These properties can be regulated by a suitable choice of ligands, since the latter strongly influence the reactivity and stability of ruthenium complexes. A molecular understanding of structure-activity relationships in complexes is a key parameter for the development of better catalysts. Recent advances in nanochemistry have made it possible to better control Ru NPs in terms of size, dispersion, shape, composition, and surface finish, etc. All these properties can strongly influence its surface properties and, consequently, its catalytic performance (both reactivity and selectivity). . The use of a molecular approach, that is, the study of the interface between surface atoms and stabilizers (ligands) by combining molecular chemical techniques (eg, nuclear magnetic resonance) with theoretical studies, allows a better understanding of the surface chemistry of ruthenium nanoparticles.
