   Sammanfattning : Heterogeneous catalysis concerns material formulations – catalysts – that can assist a chemical reaction by improving its rate or selectivity, by lowering activation barriers and altering the energy landscape. The core of catalysts are often tiny metal particles that provide a large reaction surface at a small volume, as well as low coordination sites whose type and abundance depends on particle size and shape.
