K-1. Ruthenium(III) acetylacetonate provides the lowest activation energy ever found for the hydrolysis of sodium borohydride. Ruthenium(III) acetylacetonate was found to be highly active catalyst providing 1183 total turnovers in the hydrolysis of sodium borohydride over 180 min before they are deactivated. The recorded turnover frequency (TOF) is 6.55 min-1.

Full textThe first part of the present work deals with the synthesis of new achiral and chiral cationic Ru-bis(phosphane)-thiocinnamaldehyde complexes. The reaction of the chiral hydrogensulfido complexes with various substituted cinnamaldehydes in the presence of trifluoroacetic acid gives the chiral thiocinnamaldehyde complexes. In the second part of this work it is demonstrated that the thiocinnamaldehyde complexes readily undergo hetero-Diels-Alder-reactions. The third part of this work deals with cycloaddition reactions of thiocinnamaldehyde complexes with 1,3 dipolar molecules. In a further part of this work the elimination reactions of the thiopyran ligands from the complex fragments are examined

Ruthenium alkylidenes are shown to be useful precursors for the development of new tandem processes. First, a new tandem metathesis/hetero-Pauson-Khand process is developed using Grubbs' second generation catalyst. Next, various metatheis/olefin isomerization processes are explored

Full textThe study of nanoparticulated systems for the hydrogen evolution (HER) and oxygen evolution (OER) reactions allows to rationally design new catalysts that enhance the water splitting process for obtaining H2, and thus making it a suitable alternative to fossil fuels as energy carriers. Nowadays Pt and Ir are the leading metals in HE and OE catalysts, respectively, but a huge effort is being devoted to understand the mechanistic pathways that rule both semi-reactions in order to transfer the knowledge to other metals which can be more abundant and thus cheaper. Ru appears as a feasible alternative to deeply explore the reaction steps involved in the process, because it is a highly-versatile metal which shows similar activities than Pt/Ir and which can be studied by a wide range of analytical techniques as a result of its properties. In addition, Ru is four times cheaper than the state-of-the-art Pt. This PhD work aims to develop Ru-based nanocatalysts for both HER and OER, and study the characteristics that induce a specific catalytic response. The use of the organometallic approach as synthetic methodology allows to finely control the properties of the NPs, e.g. size, surface environment, dispersion, etc. In this synthetic procedure, organic ligands can be added as stabilizing agents to halt the nucleation of metal atoms leading to the formation of the nanosized systems. These ligands can alter the chemical properties of the surface of the nanoparticles, a key feature in the catalytic processes. This methodology allows as well the preparation of metal nanoparticles onto the surface of solid supports, e.g. carbon nano-tubes, fibers, metal oxides, MOFs, etc. The organometallic approach was first developed in our group around three decades ago, and today its wide use by the global scientific community has brought a large knowledge on different nanometric systems. The development of precisely controlled nanocatalysts for their application in challenging catalysis like the production of H2 by water-splitting lies among our research interests. To sum up, the synthesis of Ru-NPs and their evaluation as catalysts for the HER and OER are described, aiming to understand the factors ruling the catalytic steps on the surface of the particles, to be able to rationally design new catalysts that make the water splitting process efficient enough to replace fossil fuels by H2.

Full textAn essential ingredient in the generation of environmentally compatible pulp bleaching chemicals is sodium chlorate. Chlorate is produced in electrochemical cells, where the electrodes are the key components. In Sweden the so-called DSA !R electrodes with catalytic coatings have been produced for more than 35 years. The production of chlorate uses a large amount of electric energy, and a decrease of just five percent of this consumption would, globally, decrease the consumption of electrical energy corresponding to half a nuclear power reactor. The aim of this project is to improve the electrode design on the nanoscale to decrease the energy consumption. The success of the DSA!R depends on the large catalytic area of the coating, however, little is known about the actual structure at the nanometer level. To increase the understanding of the nanostructure of these coatings, we used a number of methods, including atomic force microscopy, transmission electron microscopy, X-ray diffraction, porosimetry, and voltammetric charge. We found that the entire coating is built up of loosely packed rutile mono-crystalline 20 − 30 nm sized grains. The small grain sizes give a the large area, and consequently, lower cell-voltage and reduced energy consumption. A method to control the grain size would thus be a way to control the electrode efficiency. To alter the catalytically active area, we made changes in the coating process parameters. We found a dependency of the crystal-grain sizes on the choice of ruthenium precursor and processing temperature. The use of ruthenium nitrosyl nitrate resulted in smaller grains than ruthenium chloride and lowering the temperature tended to favour smaller grains. A more radical way would be to create a totally different type of electrode, manufactured in another way than using the 1965 DSA !R recipe. Such new types of electrodes based on, for example, nanowires or nanoimprint lithography, are discussed as future directions.
